Hey guys, sorry for being late on this. Well my camera died halfway through the first pull, so sorry. No vids. But to say the least, I was dissapointed.

Vortech V1 headunit, FMIC, 3.33 pulley

Made:

340rwhp and 320rwtq...ONLY at 6.1lb of boost. VERY low boost.

My tuner told me, the stock Vortech intake really chokes it off. He told me to do a AFM Powerpipe, and re-tune (only $75) and if I want after, do a smaller pulley.

The car feels good, its obviously, faster and pulls good. But, 6lb of boost killed me.

[Blackbird1084]

Sorry about the dissapointment man. Yeah 6lbs isn't much on any fi setup. Now just throw a 2.9x pulley on and get it retuned. Oh and those are decent numbers so don't feel bad.

[PhillyStyle]

Glad to see u finally got the it done...but only 6lbs even with the 3.33 pulley? That worries since I'll be putting in a similar setup. Did you check for a any leaky couplers?

[00mustang00]

hey man those are good numbers for 6psi your still pushing a decent ammount for the money you put into the kit. with just a little more you can deff make well above what you have now!

[I8ACMRO]

Do the AFM power pipe. Also try a 3.2-3.0 pulley if you're still low on boost.

[Shaun03GT]

Yea no boost leaks, but Im double checking everything tomorrow. Its accually pretty good power for only 6psi. Im just surprised it was so low.

[BakerFX4]

nice shaun... smaller pulley would get the job done for sure.

[Shaun03GT]

Thanks baker. He told me the power pipe would definatley let more air flow in, and that the stock vortech intake was the restriction. I hope so, he said typical gains are 2-3lb of boost....is that right? And usually how much rwhp per lb of boost? Like 15?

[PhillyStyle]

You could be getting pressure drop through your intercooler. I opted not to get a Powerpipe because I thougt it would add too much boost with a 3.33 pulley...now I may change my mind.

[Blackbird1084]

More like 10hp for 1psi. But if you pick up 3psi from just the pipe you might wait to swap pulleys.

[BakerFX4]

to be honest with you, going from the procharger inlet to the AFM, i really didnt notice anything and i wouldnt get it again. I would instead build my own. Ive seen some BADASS ones before that were homemade. It was badass. It was a local guy here that made it. I almost sold mine to make one like his but didnt do it.

[sharkbait]

Can someone explain these power pipe things.

[00mustang00]

basicly its a bigger intake for the supercharger so it lets more air in

[hardhitter]

6psi? I had 11psi with the 3.33" pulley and powerpipe

[redrocket]

i have the powerpipe and 3.12 pulley and im making 10psi

[sharkbait]

Can someone explain in more depth how they work? Also how would I make one?

ty though 00mustang00 reps givin

[GTRACER88]

IIRC you dynoed at 260 before the vortech. Well if that is so you are making 13.33 rwhp per PSI.

[Scott2001GT]

not bad man...but 3.33 pulley making 6 psi...something is off. Procharger(i know different) told me a 3.6 should make 10psi but I got the 3.4 just incase.

[mell0]

yeah my stock procharger pulley makes 10psi

[jivepepper]

Ebay ic's cool well but are restrictive. An ic that is designed to cool well has to do so by having more fins/surface area for the air to come in contact with so heat can be transfered. I have seen procharger ic's flow better but not cool quit as well than the 2 ebay ic's I have used. Cooler air allows for safer operation (less detonation) and more timing for power. A free flowing IC allows for more boost to the motor but higher temps so a trade off. Plus some head units are less efficent and run hotter than others when pushed.


Plus V1's like we have, have less of a internal step up ratio than the V2 and a lot less than the P1SC/D1SC. So it will take a smaller pulley to see the same boost at the motor than the others.
