Save yourself some cash.
450hp is the limit - Rods and pistons are the weak point. Powdered metal cracked cap rods.
4.10's. Your powerband is lower than in the cobra so that should work fine.
correct, you will lose peak power with the 03 intake cams.
Intake: 196 deg @.050/.392 lift
Exhaust: 194 deg @.050/.390 lift
Meat - you are correct, 3.5 tips. Now I have fart can envy now! Do they sound as good as they look? Nice ricer mod. ; )
jtl gives you the most hp.
3" tips fill out the cutouts best.
When the next cylinder's exhaust valve opens, the vacuum in the system pulls the exhaust out of the cylinder. This is what the term "Scavenging"...
Backpressure on the exhaust provides vacuum on the other cylinders, making your engine more efficient.
2004 Cobra/Mach heads for the street, FR500 for street/strip. You can use a 2001 Cobra intake.
I'd check on the gear whine, my differential does no such thing. This could be due to improperly set gear lash. Great you've done all the IRS mods...
If you want low end torque, get a power adder (turbocharger or twin screw supercharger such as a Kenne Bell) or nitrous. As you have already found...
Kind of low, yes. Get some headers and gears if you don't already have them. Then dump the diablo and get a custom chip and tune.
The best for what? If your not dragging keep the IRS.
1) Don't steal threads - it's rude.
2) Don't ask questions that can be easily answered with a search.
I'd say about 30rwhp gain.
Sounds about right - a 01 will go 150 w/stock gears. (more hp - 320@flywheel)
wtf is an o/d light?
Chip = $150, tune = $100 ish. Pulleys will get you 8hp approximately. The stock belt works just fine - it's an easy mod. It sounds like you...
As stated - Pulleys and Dynotune will get you close to 320. The tune and a chip are together. Just a chip is not as good. MAF is not worth it, but...
