There maybe something wrong with the car. Give us a call here at the shop. 763-477-9272. I need to know things like when we did the car, and the orginal owner if it wasn't you. We had a car come in here last week. It was down about 80 horse. One cracked spark plug was the problem. Three dollars later the car made big power again!

I realize they are geared a little lower, but not half-a-second worth. Getting your tune re-checked should be interesting. Good luck!

I have old design Cartek stage II Heads, small cam (218/222) and average headers (FLP's) car dyno'd 410/390 and runs 122 traps on a warm day 77` at about 700' above sea level.
This is on my 99 Coupe with an MN6.
Seen some suspect numbers in this thread.

I agree. If a person is going to look at dyno numbers, they must be obtained by a knowledgeable, and reputable, individual and must be SAE corrected and smoothed. I suspect that many numbers stated on the forum, in various threads, are "estimated" rwhp numbers, or are just the result of spikes. Those are misleading BS and mean nothing at all. It's very easy to manipulate dyno numbers. Integrity is the name of the game and where the rubber meets the road is the proof in the pudding.

Somethin else worth noting. If your fuel pressure drops below 55lbs the computer starts changing things and your tune will deteriorate over time. As long as your FP stays over 55lbs at all times the ECM doesn't suspect anything.

Hmmmm.... So I am being doubted? I can upload my dyno sheets this week and pics of my cars. Yes most of my other threads are about a 95 that I am in the process of buliding now. I also have a 69 Tri Power, is it ok if I post about it also? Why would I try to down Doug Rippie? They have offered to help with my problem and they are a very good company. But the answer to my 400 horse woes came from Randy at Doug Rippie. He said they didnt put very big cams in back in 2001 and I would need a bigger cam to put down the 400 horse numbers. Now I am looking at putting another 1,000 dollars in this car for a bigger cam. Surely there is some other way than this. I am thinking about nitrous but don't really like that idea.
I can't exactly remember my 1/4 mile speeds. I do remember the time though, it ran a 13.080. Somewhere around 115. My 60' times is what hurt me at 2.5. I was running the run flats.
Now in closing, I am not trying to say anything bad about DRM. But for a car that is supposed to be the same power of a Viper, well it's not. I have a 99 Viper all stock and it would crush the DRM car.
Oh and c5xstacy, the dyno was SAE smoothed.And a very reputable company.

A 115mph trap speed would mean you have around 365 to 370rwhp. With a small cam that's about where you will be. You didn't mention which heads you're using in your post or the size of the cam. Which intake are you using, LS1 or LS6? There's around 12-15hp difference. Using a cold air intake system will get you better results as well. It may not show up as a big increase on the dyno but at the track it's a whole different story. I don't understand the comment about DRM using a smaller cam in 2001. Did you have the work done that long ago or did you buy the car that way? In any case, let them take a closer look at your car. I'm very curious to see if they find anything wrong. Keep us posted.
Good Luck!

I bought the car new in 98. In October of 2001 I had DRM do my work. Last week they called me and spoke to me about my low power issue. They said that in 2001 they had used smaller cams because the whole industry was. Now everyone is running larger cams and pulling more horse from the LS1. So I'm kind of in a sticky situation. I live in KY and can't exactly drive my car to see them. I am thinking of shipping the car to them, but really don't want to put any more money into it than I have already.

The SAE and smoothed dyno comment was not directed at you. I was agreeing with Aquaman about another post in this thread. Why would I question your dyno as being too high? You were saying you thought it was too low. Anyway, peace to you. Glad Randy was able to answer your questions.
