My blower maxes at about 6700 I actually over spin it slightly. Remember I don't run an IC so much of this is just efficient piping you will never acheive boost numbers this high with a D1 and IC.

 

Exactly! You guys are trying to compare apples to oranges to grapes!

The D1 is a totally different animal to the D1SC, and when you take an intercooler out of the mix it makes it even more different.

That's why I hate it when people say they have a D1 when it's really a D1SC!

 

Besides having an oil feed line and a slightly higher step-up ratio, is it really that much of a totally different animal?

What are some of the pros and cons?

 

The impeller is a lot more aggressive up top. It takes more rpm to start making boost, but it comes in sooner. Despite ATI's ratings of them both flowing the same and having the same horsepower potential, the D1 actually does make more. Just ask Mike Dezotell at Dez Racing.

 

Good deal. That's what I'm running and I'm anxious to see what its limit is going to be. I'm hoping that when it's maxed out on my engine that it will be right at the point where pump gas starts to be the limiting factor. Then I'll add some water or nitrous, or both.

 

Pros a little more power than the D1SC Cons if your blower eats itself all that crap goes in the oil pan!

 

Jeff what have you done to your car to get your weight down.. I just weighed mine this weekend and am sitting at 3910 with me in it.. I'm a big guy, a solid 250lbs, so that puts me down to 3660w/o me.. I need to shave off a few hundred pounds..

 

WOW! Thats a heavy beast! Mine weighs in at 3440 (without me in it). All I have done is gone to a full tubular suspension (K-member ect.), and yanked the A/C system, as well as the spare tire and the jack. Other than that, mine still has same if not heavier than stock components. I know I picked up some weight with the FMIC, the Blower unit, and the bigger 12 bolt rear.

 

My car was weighed on professional 4 wheel scales to get an idea on what to do with the suspension. I just did all the normal stuff everyone does no AC heat airbags pretty much just a shell of a dash and only one race seat. My car weighed 3875 with full interior thats the weight it was when I did the pinks show. Many people have shaved alot more weight than I have I wish I knew how. I figure I could get another hundred out but damn some people cars weigh about 3000 I'll never get that far.

 

3875, 3910? I am guessing that is with the weight of the driver. I don't know why mine is so light at only 3440 (without driver). I remember looking in one of those friggin huge GM model books once and comparing different models and year Camaro's and remembering that mine was one of the lighter ones from the factory compared with earlier and later Z28 models.

 

mine's 3550 with driver

 

Back in 2001 when my car was bone stock, it weighed right at 3700 with driver and 3/4 tank of gas. I'm hopeing it's at least 200 lbs lighter now.

 

3910 is with me in it.. 3660 or so w/o me in it, still 200 lbs heavier than your car..

I haven't done any of the tubular stuff yet, but have ditched the a/c, power steering, and other un-needed stuff from the front. Like Jeff, I also have a TH400 (which outweighs the T56) and a 9" Rear w/ Detroit Locker (which is heavier than the stock rear or a 12 bolt) .. The 6 point roll bar doesn't help either

I've been talking about pulling out the airbags, and removing all the crap from the dash. I have a some of my stereo stuff still in the car. I also hear you can pull the front and rear bumper supports and the side impact bars in the doors (since I have the 6 point in there already) to save 100lbs or so.

Anyone want any of that stuff? I'll sell it cheap

 

Pulling the bumper supports and everything from inside the dash is going to be around 200lbs. The passenger air bag alone is 14ish pounds. Front bumper support is like 30's, rear is 20's. It all adds up.

 

I'd never sacrifice all that stuff for a hundred or so pounds. Heck, I'm sorry at times that I yanked my A/C out. It depends on what you want out of it though. If all you want is a gutted, rough riding drag car then you may want to do it. I prefer something that is still enjoyable to drive on the street (my opinion on this may also differ from others). Either way, I think it would be easier adding a little more power than creating a shell to drive.
