Hope this thread doesn't make you roll your eyes. Just lookin' for info for some mods that I'll probably do in a year or so.
Got a friend with a big mouth and a Kenne Bell 4.6 GT It's a 2002 Automatic Mustang GT:
4.10 gears
Off-road X-Pipe
Borla Stinger Cat-Back
42lb Injectors
75mm TB
90mm MAF
Kenne Bell 9 lb intercooled kit
10 lb pulley...making 11 lbs boost
Any way of hanging with him, with some mods?
I'd like to stay away from forced induction and the nitrous approach. He's claiming around 440 whp. Can I get there or better by sticking with the naturally aspirated approach?
As the current owner of an 05 GTO and a heavily modded 02 Mustang GT (11.01 @ 120 mph), I have experience with both cars. When my GT was stock it could run 13.8 @ 100 mph (5 speed). With his mods and considering the auto trans, he is probably capable of low to mid 12's, depending on driver ability. Unless he has more mods that he is hiding, there is no way he is making 440 rwhp @ 10 lbs of boost with the KB supercharger. More like 375-395. My best so far in the GTO is 13.3, so assumming you can do the same, there is no way you can hang with him without some serious mods.

I'm just taking him at his word about his mods and his HP claims. He says that KB owners commonly see 400whp dyno runs after they've installed just the 9 lb IC kit, w/ all of the KB inlet components. Maybe I'll just keep the mods to the basic bolt-ons like Cat-Back, CAI, hand-held tuner, etc...
Hmmm, he has a 9lb kit, with a 10lb pulley, but making 11 lbs boost? Odd.
Anyway, with a set of heads, cam and gears, on a drag radial, SURE you can beat him. But are you willing to drop 10k in mods just to beat this cat?
No, 10k will probably be way too rich for my blood. Sounds like it'd be cheaper to go supercharged, but I've seen a few posters that didn't recommend forced-induction for these motors. I'll just keep it simple and not worry about his Mustang. I'm sure I'll still have top-speed bragging rights with his 4.10 gearing.
As for his boost and pulleys, all I know is that I was in his car when his AutoMeter gauge indicated a solid 11 lbs boost. Felt strong, just don't see how he stands the off-road/Stinger combo as a daily driver.
LSx engines run too high of a CR to do forced induction, Sean with MDMC can get 550 hp with these mods; CNC ported cylinder heads, Custom cam and push rods, 1 7/8 ceramic coated long tube headers, 2.5 inch high flow exhaust, Custom computer tuning and Custom 4 inch air intake system. You can bump that up to 650 with a Custom D1 Procharger and a 3 Core custom intercooler.
Seems like he told me around $6k for the 550 package, don't quote me on that.
