99 Z28 vs 99 Cobra Well its getting close to summer and it has always been a race between my buddy and I, at a 50 mph roll last year we were door to door, at the time mods were....
99Z28- P/P TB, Lid, smooth bellow, free air, dumped stock exhaust no muffler.
99 Cobra- ORX or H not sure, I think H, Flowmaster catback, K&N intake, Diablo tune.
Currently I am installing LS6 intake, ORY, and LT's, and new plugs and wires, and a mail order tune.
He just bought LT's, and has a lowering springs sitting around, also bought a stock intake and is int the middle of porting it.
He claims he will be around 330-350 to the wheels......
Both cars are manual
Roll or dig... We will most likely do a roll first then take the dig to a track this summer.
Thanks!
P.S what will I put down?

you MIGHT see 340-350 rwhp depending on the dyno though. i know i ran my buddies 96 cobra that had intake and free exhaust and a short throw shifter, when i had manifolds and cats i barely beat him but when i had LT's he had no chance and this was from a dig. as long as you can drive you should be good IMO

I don't know a ton about those Cobras, but don't think he will be near 350 at the wheels, I'm thinking more like 310-320. I would say you should get him by 2 cars.

I agree with the hp numbers here. Hell be trapping in the 106 range with his mods so you should take him. My brothers 96 cobra runs pretty damn good from a roll(same type mods as the 99 above) but I put a car or two on him in the cadillac when it was stock and I was trapping 108 from a roll.

Cobra will be around ~330rwhp/315RWTQ with a custom dyno tune. If that Diablo tune is the handheld box tune, he's hurting himself by not getting a custom tune. I'd estimate a good ~20-25 RWHP is left on on the table with a box tune.
You'll have your hands full if he can drive and knows to keep his shift points above 6500-6600 rpm.
(See what I did thar? LOL)

Depends on the car, everyone is different. My car made 350/350 without the ls6 intake. I would imagine I am somewhere between 360-370 now with the ls6 intake. My mods will be the exact same as yours, so you might be higher than you think.
