How safe would it be to run a 10% od pulley and a Ported blower
on a '95 5spd with 90,000 kms with 2.5" down tubes into high flow cat's into a stainless Magnaflow duel in single out into 3" center section into 2.5" rear into two two chamber Flowmasters.
It also has a 76mm MAF a MAC cai,75mm t-body on a stock bottom end with stock head gaskets.I know im missing stuff but thats perty much the just of it.

Thanks.
 
a 10% od on a 94-95 is actually closer to 13-15% as the original pulley is bigger than the 89-93's that most pulleys are based on. But, the 5% pulley runs 8-10% on the 94-95. The 5% shouldn't be a problem and usually yeilds a slightly higher top end than a 10% (on the 89-93's anyway, check out the Top POwer list and look at some of the dynos where both a 5% and a 10% were tried, the 5% is higher on top and the 10% is higher on the bottom). The 10% shouldn't be an HG concern but it may cause problems with the EEC pulling timing and/or lean condidtions. Personally I would try a 5% first, plus it won't put as much stress on your blower.
