First off...Real quick question... Will the Chrome bullits from my 03 Gt fit on an 05+ Gt?

Anyways, i understand that the 05+ Gts have MUCH more performance potential than my 03 2v... But exactly how much more?

If i choose the N/A route how much power can i look to getting and what will i need to get there? Include pricing!

And if i choose to blow it what is a safe number that i can expect to get out of it?! And what superchargers do these engines seem to like the best? Again show me a rough estimate on how much $$ will be involved to give me an idea.

For your question on your wheels...I have the 94-01 Bullet wheels from summit
on my stang.No problems at all.(5.72 back spacing) Not sure if there's a
difference in your's and the 94-01.But just trying to give you some input.

Thanks bud.


I know alot of you are reading my thread and just thinking FU*KING USE THE SEARCH...... but im pretty sure im using the forums for what they are made for...

And my search does not seem to be working.. keep getting an error

General consensus seems to be that 450 at the rear wheels is safe before you need to worry about internals.

Alot of guys are getting into the high 12's with just simple bolt ons (intake, UDP's, CMCV deletes)and a tune. LCA's and some good tires are also a very worth while mod, that will help with traction. I myself ran a 13.2 (according to a G-tech unit.. so I don't nessacarily think thats its a completely accurate number, but it is 4/10ths faster than I G-tech on the same unit with stock pirellis and the lid on....) with a set of drag radials and the lid off my filter box.

O i was thinking you could get closer to 500rwhp with these engines and be safe on internals?

MexGT

u can get 500 rwhp yeah but being far away from being "safe"
425 - 450 rwhp is more than enough for stocks.

Block is good for WELL over 500RWHP...its the crank mainly...rods too...

I know the driveshaft isnt rated for anything higher than 500FWHP...so thats a starting point...

Rear-ends are built solid

I know with a KB at 8-9PSI Intercooled and a Custom Dyno Tune, I was going to be looking in and around 450-470RWHP

What do ppl think the block can support?

The Tuner at Steeda told me that becuase its cast iron...in and around 1000....but i dont know its it is THAT high...

but he told me 1000...he was running an 03 cobra with TT (lots of boost too) and he said they are the same block...?!?

So basically if we replaced with forged internals we should be able to safely attain 600+ N/A or Forced
