hmmmmmm
Have you ported / polished your motor? Headers and Exhaust? If so the STS program is almost done.... They have been working on it and I "believe" it is about $7k. (don't quote me) That M5 is a monster too! |

Hmmm... 5500 RPM in 5th gear....... Trying to do the math in my head... Uuuuhhhh.... Ummm.... Holy Crap!! Assuming standard rear end gears, you were doing close to "Where Life Begins"! Where the heck in the Folsom area is enough room to do warp 1.8? Bummer that he beat you, but what the heck, he spent a TON more money.

My car is ported, k&n, cut out the bumper for max air flow, Doug Rippie chip, Accell injectors, Borla exhaust, aluminum fly wheel, and running octane booster. The M5 was a few car lengths behind me when we jumped on it, but he caught up to me and passed me! I had just gotten on east bound 50 at Bradshaw at around 11:00 PM and it was a black M5. I am up for putting headers on my car, but will it get me to 500 hp? Jon let me know where in my area I can take my car to who even knows what a ZR1 is!

roger , GET HEADERS that is a big cork in your hp . when you port things you get the air in but with out headers its like your car is trying to breath thru cocktail straws (you know the little tiny red ones ) get headers and get a good tune fromclass guy ask around in your area who does good work one name will popp up time and time again as good . it will be worth it . you get headers and a good tune and he eats your dust. was the car silver ? wonder if it was the same guy who lost to me?

We (Ron Hanselman and I as Raptor, LLC and in conjunction with STS) are well along with the ZR-1 rear, twin turbo construction. Turbos are mounted, hot side is done, cold/boost side should be nearing completion. We expect to be road testing the fabricated prototype within 2 weeks. Will take appx 4 weeks after that to finish piping jigs, CNC polished SS piping, final test fitting, installation manual and system inventory. So, 6~ 8 weeks it should be ready to market. We are expecting to have it ready for the Las Vegas Gathering. We just finished road testing on the LT1 Corvette, single rear turbo. At 8# boost, it went from 268 rwhp to 408 rwhp, a 52% increase and 264 rwtq to 437 rwtq, a 65% gain. What really matters is PUC (power under the curve). It pulls like a freight train. The LT5, due to its stock compression of 11:1 and 4 bolt/cylinder design, will be tested by Raptor at 5# boost which is expected to result in about a 33% increase in Hp and even greater gains in Tq. Here again though, it's PUC and the increase in torque that will really show off. FWIW, I am personally aware of a TT LT5 that was dyno tested for 30 tuning runs at 8# boost with no ill effects. Point is....a stock engine may withstand more than the 5# boost we are representing as a safe level, we just can't push the envelope for marketing purposes. Go ahead and put headers on your car as the LT5 twin turbo system requires headers anyway. We will be posting pictures and progress reports here on the ZR-1 Net Registry Forum as it becomes available.

Geez! I hope you have 4.10's on the rear, or else that's about 160mph!
