Tony,
Is this true that a TB was also changed? What were the mods on the car?

You are correct and I apologize that I hadn't mentioned that....to be honest its been so long I completely forgot. That gragh came to mind purely because it was a perfect example of how a properly modified FAST can not only bring big peak gains to the table but also enhance the bottom of the curve where a stock unmodified FAST really falls short.
Also, to be fair, at the low 400 RWHP level, I would be surprised if the larger MAF was even worth 3 HP and the gains would purely be at the top of the curve. Even at close to 500 RWHP the larger MAF might only be worth 3-5 HP but if your going to the dyno anyway, for the dollars invested a larger MAF still certainly makes a lot of sense. Ive also seen threads where the gains from a larger MAF have almost been negligable (perhaps tune related).
Either way though I should have provided that info with the dyno gragh....

Tony M.
for comparisons between:
Ported FAST 90/90
Ported LS2
will the particular set-up have a big effect on the gains? for some set-ups would one intake be better suited? or would the difference in set-ups jus be negligible?
Ported FAST Price = 3/2 Ported LS2 Price
it seems like many people r not disputing the FAST having better gains than the LS2, but they r wondering if the gains justify the overwhelming increase in price.
i feel like maybe on an aggressive set-up 500+whp the Ported FAST is well worth the xtra price, but maybe for the concervative setups 400whp the Ported LS2 would be dramitically better than the LS6 and almost as good as the Ported FAST. so for the price the Ported LS2 is a better option for those individuals.

thanks to this thread, i contacted dave and picked up his DTP stage 2 cam and his ported fast 90, for way less than i thought it would be. dave my car should be done this friday, once it is ill send you the dyno results. i decided to get the LS2 tb ported by mark shanner from www.s2performance.net he lives 10 minutes from me, figured id give the ported fast its full potential.
the only down side is i ran out of money and im going to be reusing the stock exhaust system w/corsa cat back.

someone asked a question in the external section and it got me thinkin about this thread again. so i searched for it, found it, and now am bumping it after 2 months...
has anyone had a chance to do a true comparison test of ported LS2 vs ported FAST 90? same day, car, etc? i know Tony Mamo was talking about posting if he had a chance, but i havent seen it if he has.
i see LS2 intakes still going for less than LS6's and prices seem to be continuously dropping. this makes me think they are garbage and i should stop looking at them. but i still wonder how it compares to FAST (and y not an LS6 too) on a cam only or mild H/C car (something jus over 400whp)???

I am going to swap a stock LS2 intake if I can get my hands on one....at least that was the plan and I think there is a good chance of that happening.

Where can I get an LS2 intake? haha
Does the LS2 intake use the stock LS1/6 fuel rails?
