Turbo UPDATE #2

[dirtybird91]

I know what you guys are thinking, and I know I sound like a broken record. I was informed by HP Performance this morning that the Turbo project on my '91 SC will begins this week. I will be giving you guys information as this project unfolds. :cool:

[DamonSlowpokeBaumann]

FRANK ITS NOT APRIL YET!!!

hehe GOOD LUCK!

[David Neibert]

My car (93 SC with 347 v8 ) is next in line after Frank's and is scheduled to start when Franks car is nearly completed. I'm being told the installation will begin in mid Feb and I'll be trailering the car to New Mexico about a month from now.

I've been driving it to work normally aspirated for the last couple weeks just to get the new motor broken in. It looks great (always wanted a black SC) but it's pretty unimpressive in the power department and with a stock SC exhaust system it's very quiet. I'm told that will all change after the turbo system is installed. :D

[quick35th]

Good luck both you guys with your turbo projects!

Good luck both you guys with your turbo projects!

Shane

Thanks Shane! I am excited about David's V8 Turbo as well, and I can hardly wait to pick mine up in New Mexico and check his out. Hopefully I can time it so that I can meet up with David in New Mexico. The next two months show promise! :D

Damon, you are jinxing me damnet! :D :D :D

[MIKE 38sc]

Better watch it Frank there's a hoss coming to kick *** and take names! :D
I love all this diversity going on around here now with the turbo's and different blowers. :D Gonna be funny though when my little Eaton makes its debut and hands all of you your ***'s! LOL!!!!!! :p :D :D

Frank, I think Mike is calling you out. :eek: Now Mike, you know you want be taking names, just initials. You'll be too busy to get names. :D

Can't wait to hear more about Frank's & David's turbo progress and ( :confused: whatever Mike is working on ;) ).

Frank have you been dipping into the reg coffee again you know you are supposed to use decafe!

[dirtybird91]

OOPS! Sorry about that Manny! I have been drinking both lately! It's stressful stuff worring about you guys on my bumper all the time. :D

[DamonSlowpokeBaumann]

Only SC I'm interested in besides my own is Franks....And I;m still nto scared of it:O)

[MIKE 38sc]

LOL!!!! We are not worried about Mike's little HEATON! :D :D :D

You will bow in the presence of Frankenblowers carbon rotors!!!!!! :eek: :D :p

[MIKE 38sc]

I'm not calling any names here but sometime this summer a certain person will be removing part of the screen name because it just will not properly fit. LOL!!!! :D :D :D

[ThunderDave]

OOPS! It's stressful stuff worring about you guys on my bumper all the time. :D

Would that be your front bumper Frank? LOL :D

Mike, are you talking about "SLOWPOKE"? :eek: LOL

David

David

You are right David! I better chill out for now and wait on the hard evidence. :D
But be forewarned that I will be talking smack if it works out! :p :D

[David Neibert]

Frank,

Damon claims to be making 500 rwhp with his current combo (2.2 AR with air/liquid IC)...so even with the turbo, he's going to be a little too strong for your car to hang with until you get some better flowing heads and a stronger bottom end.

If he can put than much power to the ground, his car should be able to run high 10s at stock weight.

David

[tim]

Cant wait to see how this comes out. The turbo is a great idea. Cant see how a blower will stay with it if its set up right. Blowers take a lot of power to turn. Turbos are almost free power. Detuned Daves car should easy turn a 10. Now the 6 is up in the air. I would bet if everything else is right 11 seconds should not be out of the question. They do it with Grand nationals all the time.

[DamonSlowpokeBaumann]

Ok...I'll say it now..Frank....Your best as is with turbo setup will be in the 13's :O)


There...I done said it...

Me...Ill never run a ten because I will never have a rollbar in my car:O)

PS Depending on turbo size however with the proper work you can surpass that easily..Afterall there has been a twin turbo 1400 hp SC motor out there already:O)

[tim]

13? You have to be kidding my pos car ran 13.50 a turbo should be a lot faster than that.

[MIKE 38sc]

Just because you will not have a roll cage does'nt mean you cannot go that fast. ;) :D :D :D :D

[DamonSlowpokeBaumann]

Frank has a stock motor. Stock cam..Stock everything...That is why I predict 13's.

Throwing a turbo kit onto a stock v8 mustang motor will give you maybe 2 seconds. And that is going from naturally aspirated to boost

Here we are taking off one power adder and exchanging it. Stock Auto runs mid 15's......I'm giving him 2 seconds for the swap which I think is pretty generous.

Hell I wish Frank only the best being hes a good guy..But I would try not to be so optimistic as to say taking off a blower and adding a turbo will remove more then 2 seconds....You dont agree?

Regardless..Frank..I wish you only the best and I hope you know that. WHat youre doing is what I should have done...But I wanted an SC

[Randy N Connie]

If the motor is all stock.My guess is that FRANK will gain 80 to 100 hp
max.So I would agree with Damons prediction of Franks new ET.

I think frank will have around 300 to 320 rwhp.with 15 pounds of boost.

Once Frank has the turbo set up.It will be easy to build the motor up
for more hp.Cam a little head work,maybe beef up the bottom end if
he wants to go over 385 hp.Frank will easily reach his goals.It may
just take more than a turbo.But then I do not know what Franks goals
are.

AT any rate of the outcome,GOOD LUCK FRANK!!
We all like you fast or slow.Randy

[specops_SC]

double post.. :o

[specops_SC]

Me...Ill never run a ten because I will never have a rollbar in my car:O)


im gonna go with manny on this one damon. no roll cage just means the techs are gonna flip out after your 10 and post pics of you and your car all over the track to make sure you never run there again.. i mean, i doubt any of the will know what the car is capable of. oh, v6 you say? all right, heres your number :eek: :D

Moses

[dirtybird91]

You guys are pretty cool! I am going to go on record to say that I am challenging Damon to a race and the winner will take home both SC's! My terms are simple: We will have a foot-race for 100 meters! Damon you better bring some damn good track shoes! :p :D (JK)

Also I apologize for not responding, but I have been away from the office for a few days. I have read predictions about what quarter mile time to expect from the stock 3.8 block. This setup should do better than 13's with the stock block. Although the block is "stock" the setup is far from stock. First of all the turbo should show at least a 50hp advantage over an SC with similar boost. The stress on the belt driven system robs the crank on SC's. HP Performance would not agree to accept my Supercoupe unless it was stock being that they will have customers to show hard numbers at the climax of all of this. There will be many differences in my Supercoupe after the turbo kit:

Differnent Intake
Upgraded Fuel Injectors
Chip (Or engine management system)
Custom Headers for turbo system
Custom Exhaust
Possible Alcohol Injection system
Custom Front Mount intercooler
Cold Air Intake
Art Carr's Extreme AOD w/2500 stall
Mike38sc's custom radiator
And oh yeah "my big a$$ 11-inch jungle boot on the gas pedal!" :p

Now, with that said- My prediction (like David Neibert's) is 12's. But as they say, "Opinions are like @$$holes" :rolleyes: To be totally honest with you guys, my personal best was a 15.4 so 13's would make me happy. :)

[DamonSlowpokeBaumann]

I still say 13's!!!!!

But once you get everything running..I think 12's will be achievable once you start modding the motor itself:O)

And I am in no condition to race anyone!...On foot haha

Are you saying you are scared Damon? :D :D

[David Neibert]

If Frank can get 325 rwhp by adding the turbo system (I think he will) the car should be able run high 12s.

What size turbo Frank?


A local GN made 250 rwhp and 340 ftlbs with almost no mods and a stock turbo. GN guys get into the low 12's with the stock turbo. :eek:

turbo n/20 flux capaciter it dont matter non ported heads, stock cam, stock valves stock springs, I say mid 13s. take note of my prediction mid 13s!!!

we will see when he gets it going but thats what i expect, we need a list of predictions to see who comes closest. maybe a poll hmm yeah a poll.

[David Neibert]

Manny and Damon,

I've seen Dave Dalke's SWB make 288 rwhp with a warm motor and everything stock except an MP FMIC and a 2.2 whipple. It would have made more power if it didn't run out of fuel.

If that car can make 288 with a whipple, I'm sure Frank's can make 325 with a turbo, more fuel, long runner intake, and an FMIC.

How quick the car is, will depend on how soon the power comes on.

David

[dirtybird91]

A local GN made 250 rwhp and 340 ftlbs with almost no mods and a stock turbo. GN guys get into the low 12's with the stock turbo. :eek:

We should be getting some feedback from HP Performance soon. They will likely contact me in a few days with questions in reference to what suits my needs. The turbo will be sized according to the 3.8, but that's all I know right now. I will get back to you guys ASAP!

Also RANDY!
I LOVE YOU TOO MAN!!! :D :cool:

[DamonSlowpokeBaumann]

Dave keyword 2.2 and Front mount.

We all know how much power a 2.2 liter autorotor can make...Take a look at what it can do ona latemodel cobra..So it can flow plenty to make power.

I thought Frank was going with a short runner box type intake...FRANK?????

The same car with the 1.7L AR made 295rwhp (by 4500rpm). ;) The stock intake and cam is going to kill Franks car to a point on the upper rpms. It should make about 300rwhp through that AOD though. I think the Mustang guys made 340rwhp with a stock engine but he didn't have the heavy SC crank and I believe it was a 5spd car.

[XR7 Dave]

I predict the first few times out will be 14.xx runs as Frank figures out how to drive the turbo. Of all the mods listed, non are going to add HP to the turbo. We often think of all those cool things as power adders for SC's, but in reality they are just handicaps for a lousy blower. A good boost generator makes all those other parts more or less insignificant.

[super red91]

Twin turbo v6 mustang 399 rwhp :) , stock bottom end, intake, heads, cam, and tranny. This is also through an automatic with 14psi.

That is a split port motor that started out at 200hp instead of 140. ;)

[super red91]

I know im just fueling the fire :p

[super red91]

Thats still 200+hp more at the wheels since im sure the 200hp from the factory is not at the wheels. Do the split port heads bolt up to our block?

[DamonSlowpokeBaumann]

Well with the turbo lag and a heavy car with the AOD..Frank may just have a good launch..But we shall see

Just wait till he puts a real motror behind the turbo setup though

[Conan56]

I think Franks Car will do alright Maybe mid to low 13s

The thing that is really Going to hurt this turbo project is the 4000.00 plus price

I can tell you that on my 130k 87 Gn I did very little work and had the car running 12.8 @108 all day on street tires with the following work

Chip
Cold air intake
Adj Wastegate rod set for 19lbs boost
160 stat
Exhaust dump
Adj Fuel pressure Reg
Bigger Fuel pump

That was with stock INJ Stock I/c Stock turbo

Franks Car should be right near those numbers
even though the SC is about 200-300 heavier

The GN heads stock Dont seem to Hurt performance by too much
Ive seen Guys run low 12s on stock heads and cam and these heads
The stock GN heads flow about 145CFM max on the exhaust side

[XR7 Dave]

Thats still 200+hp more at the wheels since im sure the 200hp from the factory is not at the wheels. Do the split port heads bolt up to our block? Yes, you could bolt the whole upper system on your motor. Not sure it's worth it though. SC heads properly ported will outflow the split ports on the exhaust side and all you'd need to do is port the stock NA lower and build a boxed upper and you'd be better off than the split port guys.

Or not. :)

Dave,
You may be onto something here! I went from driving a bunch of Mustangs and eventually went high 12's in my 2k GT after spending a wad of cash on it. The Supercoupe was far easier to handle, but far slower. I suspect that the turbo will have a different power band than i'm used to. Maybe I can learn a few things from you guys at the next meet. I will definately be trying to get myself out there. I have an extra block and heads in my garage that are in need of serious money. My plans are to incorporate the new short block when I can afford it. :o
I will appreciate any help you can offer when it's time to tune the new stuff.
Thanks in advance. :cool:

[super red91]

Well forget that idea. I always thought ported split ports would be better off than ported SC heads, guess not :rolleyes:

While your waiting , watch this video of another HP customer's car. I'm sure it will cheer you up. I hope mine sounds similar when done.

[DamonSlowpokeBaumann]

What your hearing is wasted power via blowoff valve

[David Neibert]

What your hearing is wasted power via blowoff valve

Damon,

I thought the BOV was only supposed to vent when the throttle plate is closed, and that all the hissing sound on the video (when on the throttle hard) was from air entering the turbo.

David

[mannysc]

hmm I thought a blow off valve was a plate that blew open and closed via springs , when max boost was achieved and a waste gate was the adjustable boost regulat :D r.

[super red91]

Dave, you right the BOV lets the air out since once the throttle closes it has no where to go. If it cant get out you get compressor surge which isnt good for the turbo. Sorta like the turbine wheel spinning one way and then the tb closes and all this air wants to go back into the turbo, thats where the BOV comes into play and lets that air out. The wastegate is a valve in the exhaust that opens once the turbo has reached its desired boost. The wastegate opens and lets exhaust bypass the turbo so the boost doesnt keep climbing.

[DamonSlowpokeBaumann]

I didnt hear the wastegate dumping as its probably routed back into the exhaust...Sounded alot like the BOV leaking..I could be wrong however..I'm making a hell of alot more boost then that and my car is 10X quieter as far asall that nonsence noise is concerned.

No the BOV shouldnt leak boost under full throttle. Like Dave said it is to protect the turbo from compressor surge...But thats what it sure does sound like

[David Neibert]

Damon,

I think you may be correct, because most of the HP kits have the waste gate vented to atmosphere and I didn't hear any noise from excess exhaust pressure being vented. I wonder if the guy had the waste gate closed and all that hissing was excess boost coming out the BOV. Is it even possible for that to happen ?

BTW, I'm having my waste gate exhaust plumbed back into the down pipe.

David

PS: This car has the same turbo I'm supposed to be getting and I'm pretty sure it's wastegate is vented to atmosphere. About the only hissing I hear is when the throttle lifts and the BOV vents.

http://www.turbochargedpower.com/Movies/ben-run2.mpg

[ricardoa1]

Its cool that they atleast have it on the web site as a comming soon kit.

:)

I bet it will be pricey all the other kits are going for 7g :eek:

[MIKE 38sc]

Yes David its possable to use the blowoff valve to help regulate the peak boost pressure. Thats why there are several different types of blowoff valves some with replaceable springs and adjustable spring tension. I would and have plumbed the wastegate back into the exhaust system on any street car however for a pure race car I just dump them into the atmosphere. :)

[DamonSlowpokeBaumann]

My car dumped.....Sounded liek a volcanoe erupting under my seat..haha
