Basically I'm trying to decide which route i want to take. There are WAY TOO many threads of turbo vs surpercharger. But, what im trying to do is decide between these two kits. as both are street friendly if i can say that. My motor is not forged yet. nor do i have heads yet. but im trying to decide if the switch out of ntirous scene is something i really want to do. This is not a drag car. You can see all my mods in sig but this is mainly a toy for me i want a good low 11 second car for now that is street driven. and later when i go with heads and a block will i up the boost. so i pretty much want what my nitrous offers me now. 500hp to the wheels but i want it there all the time.

thanks

D1SC, but I'm biassed. The thing is cheap, and makes stupid power.

 

being biased is ok too.. are you running the front mount or the kit just the way it comes from ati

 

I have the stage II D1SC with the twin intercoolers. They're way bigger than the stage 1s and let your cooling system stay functional by not blocking the radiator. This is important to me living in Arizona.

I needed a cam and a fuel system to make my numbers, which means you can clear 500 no problem with the base kit. This is also my daily, so I wanted it to be streetable. Below 3.5k, it's still very docile.

 

yeah i saw that... they come with the 4" thick dual intercoolers. are you running the 8 rib setup, or is that standard in the stage II

 

Turbo all the way. More efficient and no parasitic load on the motor. You'll also have a much better torque curve all the way through. Either way you're limited to 500-550rwhp with the stock bottom end but you already mentioned your hp goals...

 

yup my goals right now are pretty basic right now.

 

I'm on the 6 rib atm. It's only $475 to go to 8, but I wanted to see if there's any slip with the 6. It turns out that the blower idler pulley wraps the belt like 85% around the blower pulley and I haven't had any slip. I'm sticking with this until the belt decides I need more grip. For yours, I would stay with the 6 since I haven't had any probs.

 

Or check my numbers?

 

Let me rephrase myself. You are SAFELY limited to 500-550rwhp with a GOOD tune on the stock bottom end. Any more then start counting you days... (He already said he is only looking for 500 anyway).

Drewstein, no harm intended and not bashing your setup. Those are very impressive #s for stock bottom end. You're on the vertical limit of what that motor can take. I don't know if you read longrange4u's thread but he also was running over 600rwhp thru the stock short block but it was shortly lived. He blew the #7 piston. Honestly, you'll probably be in the same boat soon enough if you continue to run 640rwhp... JMO

 

TTi race kit. Sorry. If you end up with a blower make sure you start with an 8 rib.

Good luck,

Mark

 

I read his post and I'm going to try to perfect it a little more. If mine takes a dump, then hopefully we took a step forward with our knowledge of what makes the block go pop. I know my tune is better than what he was running since it has 10 degrees timing in the upper band. Detonation won't kill mine, pure force on the piston may however.

 

I'm just doing testing to see what the 6 rib holds. The belt wraps great, if it slips, I'll upgrade.

 

Get a rear end first!! 12 Bolt or 9 inch what ever? Then HEADS? Than TTI or P.C.
Later
Coconut!

 

tti street kit

 

Oh yeah, the voice of reason has made a point. Maybe make sure you're not going to be pushing the damn thing home.

 

I might be taking this in the wrong context, but the turbo is going to give you full boost way before the blower. This of course assuming exactly which turbo you go with, mods, etc, but thats how Ive understood it. I had a vortech on a ford and I didnt even start making boost until 3500 rpms. I peaked at 5300. Since then, and reading a bunch on the forums, I am a turbo guy. I have yet to get one, but that is most definately where I am going.

I vote turbo

 

I'm having basically the same dilemma, only you are a few steps ahead of me

 

completely opposite. id say depends on your goal, if your going to be driving this on the street alot, go withe d-1sc. with the tti kit there is a little ground clearance issue, if you don't mind that and want the pimpness of having a turbo then you know which way to go. both can make more than enough power for any DD.

 

TTi gets my vote! LOL No arguing with the numbers.
