The H/C/I swap came after the supercharger and after the nitrous, so I couldn't give you an estimate on those.

The closest think I had to a "stock" run on the car was when it had O/r H-pipe, flowmaster 40s, UD pulleys, and a CAI (stock headers.) That was 190ish. I can't recall the exact numbers unfortunately. Only did one pull on it and it was right before the S/C swap. Didn't waste time tuning, etc.

I also haven't run it since the swap because it isn't tuned yet. Well, not enough to go WOT. Just got my tweecer 2 days ago and just got the car running again last night, lol. But before the H/C/I I had 320 RWHP on S/C, water / methanol injection. It was 430 RWHP with a 100-shot of nitrous on top of that. I know, it was 110, but it was supposed to be a 100-shot, lol.

i havta say your car is amazing dude...are your internals factory?

On an otherwise stock Fox 5.0, a 70mm MAF (such as from a 94-95 Mustang) will gain 5-7hp.
These results are covered in the dyno book by Holdener.
With your cam, it may be worth more?

A 65mm TB will probably be fine while you have that cam.

The 70mm MAF from a 94-95 Mustang will be cheap if you can find it in a j/y. You will just have to find an inlet adapter for the air filter; which can be found for $35.
Then stock pile cash for the heads...

Yup, just the factory crap inside. That's why I don't want to push too much more HP or TQ. I've heard some sat 450 RWHP is about hte limit, others say 500 is the limit. Either way, I don't want to push it any further. It's still streetable right now. You figure if I don't spray then it's only 320 RWHP at WOT. But if I'm not WOT, then it's nothing more than a N/A car.

+1 on heads first very very restricted, you will be happy

what year explorers did the gt-40 heads come on? I dont want the P ones caus i cant afford another set of headers right now. and will i see that much gain with just heads? i mean will the stock intake and tb be able to handle the increased flow?

grumpyphillips

Pre 97.5 explorers had the GT40 heads. The stock intake and TB will be able to handle the increase but if you can go ahead and upgrade them at the same time as the heads.

I'm spraying only a 100 shot cause I dont want to crack ym block so I'll put put around 410 rwhp

You might want to go with even a 65 mm throttle body. Bigger isnt always better. If you go to big you will hurt yyour peformcane down low. I have trickflow heads trickflowintake etc. and I'm only doing a 65 mm on mine.You want the maf to be bigger however.

sam, i remember you saying u got the whole explorer motor, so why dont u freshen the block and use that as a buildup on the side? thats what i plan on doing. i plan on going 12s with thumper ported gt40s a B cam and thumper ported lower gt40 intake....then im gunna have upr for suspension including kmember and a set of drag springs.......12s shud b ok. if not ill spray it lol
