Alright I'm hoping that we can get enough people to submit there setups so then we can help eliminate the weekly questions of how much boost on X combo. Hopefully this will help out alot of people with new combo's etc and hopefully make it a sticky. So here's what you need to post

Year of Car and what year timing cover you have. Different Years have different belt wrap configurations I'm pretty sure.
1. 2V or 4V ( List what type of Heads, B-heads, C-heads, TFS, Stoke etc)
2. Type of Blower
3. Big Bore/Stroker/ Compression
4. Ported Heads?
5. What Cams?
6. What intake? (aftermarket, Ported, Ported Short Runner, etc)
7. Intercooled(A/A) or Aftercooled or NO Cooler?
8. Exhaust Combo?
9. Pulley Combo (blower pulley size, crank pulley size) and belt length if you have it or remember
10. Amount of Boost you are seeing at X RPM.
11. Powerpipe?
12. HP/TQ

I'll go First
Current:
1. 2V or 4V ( List what type of Heads, B-heads, C-heads, TFS, Stoke etc): 4V C-Heads (04 Cobra)
2. Type of Blower: Vortech JT Trim

6. What intake? (aftermarket, Ported, Ported Short Runner, etc): Sullivan Lower with a Berry Motorsports Upper
7. Intercooled(A/A) or Aftercooled or NO Cooler? Custom A/A with 3.5" piping
8. Exhaust Combo?: Kooks 1-3/4" Primary, full 3" off road exhaust dumped.
9. Pulley Combo (blower pulley size, crank pulley size) and belt length if you have it or remember: 15% O/D Crank, 3.33" blower, 115.3" belt
10. Amount of Boost you are seeing at X RPM. 16psi@7000rpm
11. Powerpipe?: Custom

Its a good thing you have had three setups Chris...Prob enough to get this one to sticky already!!

I'll post mine up when she is all done. But so far methinks I will have 16 psi with a 10% OD crank pulley and a 3.33 blower. Stock manifolds to a magnaflow catted h pipe on 298 cubes and 8.5:1 Comp. Stock B heads and cams, ported stock intake.

awesome man. good thread. hope it kicks off well. I may have already asked you, but i'm gonna be running a very very similar setup w/ a T-trim, and 8.5:1 w/ 04 cobra heads (but 04 cobra cams as well on a wap block) and no long tubes. do you have any issues with it dogging at low rpms w/ the compression ratio? i have 4.10s to pick it up a bit. nice numbers too, hope i can be in that ballpark.

Thanks man. No I have no issues at all with down low torque.

Stroked out it woulda been 5.3? Shit would have been off the charts son!!!

Yea it would have been a 5.3.. I think I would have helped a bit lol.. Maybe a bit closer to that 700rwhp mark on pump gas that's for sure :eek:

And that right there the 7.3k RPM makes me miss my B-headed car so bad.. That effing thing pulled until I either floated a valve or decided to shift!! I can't wait to see what it does with a built motor!

1. Stock 03 Cobra heads
2. Procharger D1-SC
3. 5.3L big bore stroker/9.5:1/01 timing cover
4. Unported heads
5. Ford GT cams
6. Stock 01 intake
7. Procharger 3 core intercooler
8. Bassani mids, Bassano O/R X, Borla Stingers
9. 12% overdrive crank pulley/3.9" blower pulley/110" belt length
10. 14psi at 6300rpm with a good belt
11. Anderson powerpipe
12. 496/469 on a Mustang Dyno at 12psi on seven cylinders and running out of fuel. I never made it back after fixing everything.
13. 91 octane fuel. 12 degrees of timing.

Unforetunately that blower has died. I sent it back to Procharger and it would cost me almost as much as a new one to have it rebuilt. So while I'm saving some money I'm trying to decide if it's time to step up to an F1A.

great thread idea, may also be handy to include what fuel is being used and timing if known
