RWHP vs Trapspeed?

peedeerooster · #1 (**permalink**) 04-06-08, 09:43 AM

I am modding my CTS V to a little over 400 RWHP. Does anyone have one in the 410 to 425 RWHP range that has any trap speeds in the 1/4 mile that they can share. Just wondering were it will end up in trap speed. Thanks

Haven't had mine at the track yet, but I'd guess somewhere in the mid 12s depending on driver.

112-115 with a pretty good run.

duh, I guess he did say trapspeed didn't he. Ya, I agree with Jon.

yea 115 would be a target. Wiith our cars its all about learning to get the first 60 feet down pat. Sub 2.0 is hard, but should and can be done.

Trap speed is not going to change with the 60' time like ET will. Trap speed should be alot more consistant. But any way would still like to see it.

In these cars trap speed is more likely to vary than most, due to the amount of babying you have to do to get them to leave without hopping. If you could leave hard, I would add a solid 2-3 mph to my estimate.

I have only had it 2 weeks now and I have already read enough about the rear to know I need to resist the temptation of running from a dig. Besides I got a mustang for dig racing that I can side step the clutch at 6 grand. I guess I will have to cough, cough rice race and run from a roll with the V. Looks like I have a car for running from a dig and another car for running from a roll. Besides the added weight of the CTSV doesn't mean as much the faster you go.

The mustang in the garage with a cover on it that is set up for the 1/4, pulls low 1.50's 60' time. The CTSV is not remotely designed to run from a dig. The rear would wind up on the pavement in peices. I was just wondering on the general trap speed because I want enough RWHP to pull on a new BMW M5. Gotta keep them where they belong for us american guys you know. I need to know if I need heads and cam or cam only. I just got to do it because most of the people that I know that buy high dollar foreign cars have a snooty attitude and nothing tickles me more than busting that high falluting hiney with this old american iron.

Cam only and you'll be able to pull an M5. With heads it won't even be close.
