SUPERCAR challenge: 'BEST' results for each car posted on Car and Driver website!!
Re: SUPERCAR challenge: \'BEST\' results for each car posted on Car and Driver website!! The times were not achieved at a dragtstrip, but a straightaway on an oval racetrack (MIS). The instruments used to measure times were not the same as those used at a dragstrip. There are many factors that...- LTHL VPR

650Hp to 800Hp = mid 12s ?
1Bad- I do agree that MPH in the 1/4 mi. is a solid indicator of horsepower at the dragstrip. I wish the Car and Driver test was performed at the strip; I think the numbers would be more realistic if they had. For the sake of the article the 1/4mile times and speeds were recorded from a...- LTHL VPR

650Hp to 800Hp = mid 12s ?
Ken- I totally agree with you! We brought our dyno run from just 2 days earlier, and we inquired with Car and Driver about setting up a dyno event to measure the REAL POWER these cars were putting to the ground. They replied that there was no dyno nearby and that the AWD car (Porsche, GMC truck)...- LTHL VPR

650Hp to 800Hp = mid 12s ?
Yeah. It looks like HMS was similar to us in that their fastest overall time did not necessarily reflect their optimum acceleration, 1/4 mile times. However each of our relative speeds given our rwhp makes perfect sense. It may be confusing because some tuners chose to use rwhp numbers and...- LTHL VPR

650Hp to 800Hp = mid 12s ?
Although I can't speak for anyone else, I can tell you that we did run in the mid 11s at over 130mph. The numbers quoted in the magazine reflect only 1 run; the fastest overall run for the event. Whatever your times were for this particular run, were the ones quoted. Although this run (#4 of 5)...- LTHL VPR

Car and Driver super Tuner Shoot Out
MASH- Not exactly sure. There were lots of other variables in this event. For instance, the LPE car was putting down some serious power because I believe it was also using water injection which can increase power considerably; enabling the car to run more boost and still resist detonation while...- LTHL VPR

Air fuel mixture (where to test)?
I would highly recommend that you weld in an additional bung to your exhaust system, and use it for measuring 02 using a high quality A/F analyzer/monitor. We do not recommend that you remove your O2 sensors and replace with the A/F monitor O2. Depending on the bank you use (primary/secondary)...- LTHL VPR

Help, need temp exhaust fix for 103 dB
Add stock cats (more restrictive than high flows= less noise) first. If still too high, try adding another set of mufflers. You may make it with just the cats.- LTHL VPR
