Intake manifold design considerations.....

looks cool but Whats a Inverted blower?

I got acts down to low 100s with iced water in a water to air ic i home made on a104 deg day and 80s deg f on a cool day again with iced water pumped thru at a higj speed slowing down the water raised the heat . so with a water to air ic i see this setup kickin some butt . more boost more fuel
 
Manny..English please? :D

Apparently for whatever reason the methanol didnt make a huge difference in dropping ACT ..Which makes sence when using e85. If it were standard gas youd see a difference for sure. Something doesnt seem right though with 200 degree temps..I'm sure its either a mistake of some sort reading wise or somethinsg seriously screwy. I have a couple of buds that do e85 conversions for a living along with the tuning involved. If I talk to them Ill see what they say
 
damon schloß oben dich verstehen, was Im sagend. ein stpid Ruck-O.K. nicht sein.

oder krank deinen Gebläsekasten ha ha ha gerade oben verwirren scherzend



in english
damon shut up you understand what Im saying. dont be a stpid jerk ok .

or ill mess up your blower case ha ha ha just kidding

Damon, this vehicle is fuel injected.
 
I know and it has a 2.0 A/R with the new lower intake inverted with E85 correct?


When using e85 as a fuel I wouldnt expect meth injection to cool intake charge temps. At the same time I wouldnt expect them to be 200 degrees either. So somethings up. Thats what I was saying

Also there was mention of hittin knock. If you have the AFR commanded properly it could very well be a timing issue. From my understanding (not experience) both are way different.

The people I know that do e85 conversions were on newer fleet vehicles. Of course now they have flex fuel vehicles but they did it before that came around. They also did propane convertions as well.

I'm sure you guys will figure it out one way or another.

I;m just curious of the outcome

We never really got to the E85, the 200F was when we were running 93 octane gas.

On a port fuel injected vehicle the fuel used will not have any effect whatsoever on the temperature of the air in the manifold as the fuel has not been introduced yet. Think about what you are saying here. E85, gasoline, diesel, or straight nitro methane = same intake manifold conditions.

At the same time I wouldnt expect them to be 200 degrees either. So somethings up. Thats what I was saying
And why wouldn't we see 200 deg? Ambient temps were around 65 deg, and when you consider that a twin screw generates boost internally at all times, it follows that there will be a temp increase at all times. I have witnessed this in real life on all AR blown cars. The temps that we were seeing during part throttle operation were around 150-160 deg. I would consider this to be normal. The temp rise due to boost alone at 15psi is substantial so 200-220 deg is absolutely great considering an Eaton generates about 340-360 deg at similar boost levels.

Also there was mention of hittin knock. If you have the AFR commanded properly it could very well be a timing issue. From my understanding (not experience) both are way different.
First of all there is no mention of knock. Please read carefully. We chased false knock signals for a large portion of the day before concluding confidently that we did not in fact have knock. I realize that using a knock sensor while tuning is generally not recommended but in this case we were being careful, to our own demise as it turned out.

So are we. Preliminary reports such as this are one of the drawbacks of attempting to do something like this in the "public eye". We had no intention of reporting anything at this time because the whole thing is still very much in the development phase. We didn't want to start a whole discussion on what might be wrong because we mostly know what we have to do. The only reason anything was posted at all is because people were asking since they knew that testing was planned for last weekend. People wanted answers and you got them, that's all. We learned a lot about the combination and have a lot of data from which to make changes which is a normal part of development and isn't normally shared with the whole world on most projects. ;)

We know what the setup is capable of, we just want to build a product that lives up to everyone's expectations for more than just one or two dyno pulls. :)
 
Nice read....Whew all 16 pages tonight....

Glad to see there are some sickos out there with the need for speed...And nice to have this brought out to general public...

Keep at it peeps...Youll get it.....

David ypur probably right. I recall an issue with a 2.0 ar and I think I remember the photo showing a whipple come to think of it.
 
Mike,

Are you expecting to get this sorted out and tuned prior to the Dayton meet ?

David


I am slowly working that way. The wife is having me redo the kitchen which is taking up a lot of my hobby time; penance for buying the 67 cougar. I have done some "auto" calibrating on street with the E85 and it seems to run pretty good. I hope to hook up with Dave for some "at boost" tuning prior to the Dayton spring meet. Running the E85 the exhaust note sounds different and the exhaust smell like "pop corn". Just kidding on the last part. See ya in a few weeks.

If you are running E85 intake temps would still be the same as on gasoline. However, knock resistance would be higher do to the cooling effect of the alcohol in the fuel being sprayed at the back of the valve.

I have done quite a few E85 conversions myself, have we met before? I always wonder about people’s identities on the internet. You never know who you have met and who you know.
