boost can you expect from a top swap 3.8 pulley with an the ss intercooler?

i would think a loss of a lb or 2

is that good or bad? im not sure about boost or psi its all new i only drove N/A's haha

the i/c wont up boost. until you drop a pulley. you will see right around 5-6 lbs of boost with a 3.8 pulley

i dont mean to feel stupid but is that alot? how noticable will it be?

yes. you will notice a difference. it will drop you over 1 second in the 1/4.

so what do you have to do to drop from the 3.8 to a lower size?

Get the specialize puller from a vendor and put on a smaller pulley. Stock, the gtp sc is putting out I think 9-10 lbs boost.

Actually, I may be wrong, with my 3.4 on there I am getting 10 lbs.

so why cant i start with a smaller pulley? i thought you had to mod your enginge what do you have to do so that your enginge can take the smaller pulley?

You have to do AT LEAST an intake, u-bend delete, and a new PCM. To be safe I would get a 3" D/P w/ a high-flow cat (includes u-bend delete) as well as a nice intake. Then you can drop to about a 3.5-3.4"

Oh and the stock 3.8 will get you to about 6 to 8 psi of boost.

You can run it with very little mods, JUST RISKY, as in Knock Retard. I have all the available mods and I am seeing 6* kr at WOT. I am in the process of tuning to get the best out of it. The PCM I got from ZZP is pretty generic. The shifts are nice, but you definitely have to tune the PCM for your mods and each car is different. I did my first tune a month ago and I gained a bunch of gas mileage and lost some KR.

im looking at which headers to get im looking at the tog or slp with a 3 dp im looking at a cai so i should be all set ... cause i want to work up to that whipple supercharger and be the first L36 whippled haha

Dude....that would be sweeeet. I say do it. Now.

dude. slow down. look at my mod list and i am still apprehensive about dropping a pulley size. All you guys are forgetting, his car has an L36 bottom end. These L36's werent made for boost. you have to have lots more supporting mods to even think about dropping pulleys and whipples etc.

L36/L67 have the same bottom ends to my knowledge. Only the pistons are different.
