I'm about to rip my C5 vert apart, thing has 200k on it, so I figure I should probably rip it apart and redo the bottom end. I can't just pull my car apart and put it back together the same way, though.. that would just be depressing.

So, I'm considering going with a supercharger. I'd like to make around 600RWHP while keeping it as drivable as possible. I enjoy driving the vette (unlike some of those guys who just leave it in the garage to look at! :P), so I want to be able to drive it to work if I want to, or whatever, you know?

I'm considering a P1SC as it seems to be in the range of the power I want to make. If I went with something like that, what kind of things do I need to be reading up on and ultimately purchase?

Outside of what a standard SC kit comes with, what else needs to be upgraded? Can the top end stay stock?

 

Is it worth upgrading the throttle body and/or maf at this power level?

 

If you're looking for 600 RWHP I'd pick-up a set of LS6 heads for cheap have a set of new Patriot Gold Springs installed. A set of COMETIC head gaskets and head "STUDS" not bolts "STUDS"

Then have the bottom end built with forged parts (Do it right the first time) go 10.0:1 compression (this will give plenty of room to play later)!

Pick-up a Blower cam (These are usually very mild and very tunable, can't even tell the diff from stock) and have it installed at the same time.

P1SC-2 System is good with a 3.85" Pulley @ 10.0:1 you will easily and safely be in the 600's!

Make sure you have plenty of fuel, BAP, 60lb Injectors at least, LPE fuel pump at leat, RACETRONIX Fuel Pump Harness! a Methanol Injection Kit will be optional (for safety, keeps things cool in the cylinders )

2 BAR SD Tune should be in order for FI so talk to the tuner about the 2 BAR sensor (If you need the part number let me know)

Gauges - Fuel Pressure, Boost/Vac Gauge, AFR gauge

Your LS1 or LS6 manifold will be plenty as will your MAF! (Depending on year - if you have a '97-'98 like me then a MAF-less tune with 2 BAR SD is the way to go)

I know I'll think of more later but if you are going to go FI do it right the first time

Thanks,Matt

 

Don't forget a good set of headers--so the engine will breath.

Take a look at the above C5 that we did basically what you are looking to do. I would recommend going with the D-1SC as you won't have to work it so hard, plus I would go with the eight rib belt assembly.

Check this kit out that we put together that includes everything you need. http://www.exoticperformanceplus.com...html?item=1136 Bob

 

You don't need much at all to make 600rwhp assuming it is a manual car. Any of the base kits out there will do it. If there is a budget at all you can pass on studs, blower cam, cometic gaskets, etc. People bolt these kits on and get those results all the time.

With so many mile I would freshen up or build that bottom end so you don't end up having to go back in there soon though.

 

If I had 200K on a C5 I'd honestly put in a LS3.

The cost of rebuilding a LS1 with machine work and everything just isn't worth it. IMHO

With a mild cam and headers you can easily get 500+ rwhp NA

 

Ahhhh! yes of course that too

I actually thought he already had a set on the Vette! So if not do a set of LT's and a good X-pipe and Hi-flow cats if needed to pass smog in your state!

Thanks,matt

Vega, I'm not really interested in going with an engine swap. I decided a while ago that I do not want to go with a H/C setup, mainly because of drivability, and not having room to grow without F/I. Having my cylinders bored out so they're circular again is cheap anyway.

Headers are a no-brainer, and are actually already on the way. The bottom end is going to be built, I really don't want to have a blown engine because I cheaped out on that, so that isn't even a question of whether to do it.

Car is an 03 A4, just had the tranny rebuilt. Probably going to rip it back out again when I pull the motor to put in a higher stall torque converter and replace the rear end and those TERRIBLE gears that come with the A4.


So.. final word is fuel pump/harness, blower cam, ls6 heads, headers, and obviously gauges and a tune

I'm not entirely comfortable with any of the shops around here tuning my car.. that being said, what are my options? Is mail order tuning reliable? Or do I need to drive down to a shop in the states (I live in BC)?

 

Ok. Driveability is important to you. If you intend to put a lot of miles on your car such as you have done so far a 600 rwhp goal may be a little lofty.

I run heads, cam, LTs and 3:42 gears. I also run a Maggie which is the most reliable and trouble free blower made for Vettes. I get 500+ rwhp on a conservative tune on 6 psi without meth. I could add a couple psi and meth a get 550 but I really don't want the hassle of dealing with a meth setup and honestly 500+ with a roots blower is great on the street.

Keep in mind the guys with 600 rwhp centris are talking (bragging) peak #s and the power is not coming in til higher rpms. With a 6 speed you can run the higher rpm but with a A4 having the low end torque and power you get with a PD blower will make a lot of higher HP cars play catch up light to light.

What ever you do H/C or SC you will need a good tuner NOT mail order.

 

I'm the second owner of this car, and that is 200,000kms not miles, I figure I drive it maybe 10,000km/s a year, I don't know if that changes your opinion or not.

I was actually looking at Maggie setups, but it seemed like 600rwhp was a bit of a stretch. I've heard a lot of people love their Mag's, though.. say the sound is unmistakeable, plus having the cowled hood is pretty cool, too. You've kind of sold me on it, and the peak numbers thing is pretty true.. not looking for a dyno queen.

I guess I'm going to have to trailer my car down into the states to have it tuned then, that is a major pain in the ***.

 

And a little off topic, but are those CCW 505As on your car? They looking absolutefreakinlutely amazing. How deep is the lip on them?
