I'd go with whichever kit has proven itself for over a decade, that way you know the company will have the ability to stand behind it's product. Bob

 

Whats the price comparison between these two setups to get up and running on the street? Surely you'll need fuel upgrades but the complete kits to get up and going? Are they similar?

 

Which kit is easier to TUNE!!

 

TTi street kit, but maybe you should look into the STS kit

 

I think thats still pretty much both of them in this case.

 

What numbers?

drewstein, i think the 500 he wants would be on pump gas.

is the car lowered? do you allready have headers?

with the turbo kit you can sell your headers and y pipe and reclaim some cash towards a rear end etc... and sure you get an extra 150# of tq too

also i have never heard of a cooling problem with the tti street kit.. ati on the other hand...

in response to bob, neither kit has been around for a decade cuz the cars havent been.. but i believe the tti street kit has been available about 3 years before the ati kit.

*forgot to add; its harder to tune/easier to blow up with the turbo*

 

1) With that setup, the D1SC would trounce those numbers. If I had a 370 forged bottom end, 750rwhp would be minimum with 800 not to far off.

2) For a 500hp setup, I still think the D1SC is perfect for him. And yes, I run 91 octane in Arizona for the numbers in my sig. So I guess the numbers don't lie...

 

Whats the installed price comparisons for the 2 kits? Like total kits with the fuel upgrades needed for 450-500 hp and installed and tuned?

 

Does everyone realize that Drewstein has a corvette. The ATI vette kit is MUCH better than the F-Body kit. In the past, the F-Body kit has had cooling issues and belt-slip issues. I do not know if that is still happening.

The TTI street kit has be a fairly solid performer below 550rw and in some cases well above that. Tuning is a MAJOR concern with any turbo kit and its the reason you see such high dyno's like RyanK's.

If you are looking to grow into the kit later, save up the cash for a TTi race kit (no A/C) or the PTS kit (long wait, but has A/C).

 

Drewsteins also probably running a stick which makes a huge differance when compaired to a higher stalled auto, but I guess that's why people race at the track instead of the dyno.

 

Yes it's a vette, and a 6 speed. I don't want to be taken as "hiding" anything. I just hate peoples sigs that show every mod down to the damn headlights. I like to "drive" my car instead of having a slush box do all the work. Racing at the track in an auto car is point and click simple. Yes auto's are quicker, but the 6 takes gobs more skill at these power levels. I know because I had the quickest "all throttle" Lightning in AZ before I got the C5.

The ATI kits on the F-Bod can put down similar numbers if you build them right. The D1SC stage II kit is sweet. But this thread is about 500rwhp which the procharger will do no prob for very little $$ and a very easy install. It will also put down more rwhp than any of these turbo kits dollar for dollar for future expandability (up to 900rwhp). That 500 number can be done with everyhting that comes in the kit too.

I will say that a turbo sounds cooler when you say it, and when you hear it.

 

Turbo kit will make more usable TQ and a hell of alot more average HP than an ATI kit. My HP/TQ vs RPM graph doesn't show it but if you look at HP/TQ Vs. MPH that paints a much different picture. And in the quarter, I would walk all over your manual equiped ATI (the worst of both worlds when it comes to average power).



VS.

 

Rest assured that their Vette kit is also junk. Very few people have gotten them to work properly (belt chucking, idler failures, etc). There are a handful of people who have never had problems, even with the older brackets. Perhaps a QA issue with ProCharger?

FWIW, I've had both a D-1SC and a TT setup on my C5 and there is no comparison whatsoever. TT's win in every category.

Yeah give me a fully built 370 and see who would win. I'm running less boost, no AFR 225s, and no Meth injection just to name a few. Not counting the STOCK bottom end on 91 octane. Grats on spending a ton more $$ than me and then talking **** about how you'd win in the 1/4. Mod for mod, nothing comes close to the ATI until you reach 900+. Also look how my graph keeps going up. The ATI will make power through 7400 where I'm not even willing to take it due to the fact that I'm not willing to scatter my block for a number.

You said look at the numbers. I'll make more with less using the ATI. I'm just sticking up for the blower. No offence ment.

 

Drewstein, I have to chime in here.

First, for his goals a supercharger or turbo would have no problems meeting them. If cost and tunability are the main concern an ATI kit would probably be the best bet.

I can't see how you argue ATI domination. They are definitely good at making power, but they are not the absolute best.

Here is test done by MMFF magazine on turbo vs. supercharger. Turbo made 170 hp and 150 tq more than centrifugal, with conditions being equal.

Hot rod also did a battle of the boost a year ago or so. Turbo won that one also.

 

I think heads/cam/nitrous is the best

 

Probably cheapest/easiest route.

 

Yeah got my vote
H/C and NITROUS!!
