First of all, keep in mind that this is a weekend car for me. I don't beat the **** out of it, however, it does see full throttle every now and then. I have LG long tubes, exhaust and a callaway honker air box.. for now. I'm getting a procharger (D-1S) put on my car in ~3 weeks, along with the supporting mods (plugs, injectors, etc.). I've been told through researching old threads on here, reading through current threads and also from the guys at the shop I go to that as long as I don't consistently abuse the vehicle, i can expect longevity out of the set-up.

However, talking to another guy yesterday he was telling me to not go with the procharger because i dont have forged internals and I caught a thread on here talking about blowing up a car (#7 cylinder) that only makes just a bit more power than i'll be making with my set-up. That person said he frequents the track... but at the same time it made me wonder if I will be on borrowed time with the set-up i'm going with.

someone give me some reassurance or some fresh input.. thank you

brandon,

There's alot of guys running SCs reliably. It all depends on how much boost and the tune.

Unfortunately I'm one of the guys that had my #7 cylinder lay down on me at track. It turns out that when I had my alky system and BAP installed the boost monitoring hose was plastic and when my engine bay heated up (I was running 160mph+ on the Roval) the tube shrunk shut and therefore my Alky/BAP didn't kick in under heavy boost and I leaned out since it was tuned for Alky/BAP. After replacing my #7 piston and changing out the plastic tube to steel-braided my car has run great.

The D-1 is capable of at least 10-12 pounds of boost and on a stock bottom end that is pushing it. You may want to put a bigger pulley on it or a restrictor plate to lower the boost to around 7lbs max. If you run more than 7lbs of boost and seeing more than 550rwhp you probably should add alky for insurance.

In any case you should look at an upgraded fuel pump/BAP, new valve springs and cooler plugs. My car has a cam and loves timing so I was able to "conservatively" tune it at 588rwhp with 7lbs of boost but it goes to show you that even at that level if the Alky/fuel system is inadequate you lose your reliability.

If you stay under 8lbs of boost, have a good fuel system and a good tuner you should see plenty of fun and reliable miles out of your car

 

more power = more stress regardless of how you add the additional power.

You will end up spending more money on the car to maintain the power you have added with a supercharger just like you would would a good heads/cam package.

If you are specifically looking for reassurance the stock LS6 bottom end will hold up to the power of a supercharger. It "should" but nothing is certain.

The general consensus is to keep power below 550 rwhp and keep the AF ratio rich and low amounts of timing to keep cylinder temps lower. I would imagine an alky kit wold help fight detonation even more.

Good Luck

 

Awesome! Thank you for the reassurance. That's what I have been hearing but after reading that thread I was like, damn, maybe i'll post up a thread of my own lol

again, i appreciate the input

Elaborate a bit on that, you mean like a meth kit?

brandon

 

perfect example:

If you add a supercharger, do not expect your stock clutch to hold up to the task. It will begin to fail quickly. Plan on a clutch replacement to a stronger unit if you supercharge your car.


and yes, meth/alky, they increase the octane level in the combustion chamber to fight detonation and help keep the temps lower.

 

This may be a stupid question, but is it meth injection in addition to gasoline injection?
How much does that type of system run?

Next on the list, my plans; fried clutch/meth kit not considered:
1. big brake kit/wheels/lowering springs or coilovers (still need to research that a bit)
2. forged internals
3. heads/cam

 

You gotta pay to play

I learned that the hard way with my previous toys

 

Alky/meth/water injection is typically only done under boost and is seperate from gasoline injection. The purpose of Alky is to lower your Intake Ambient Temperature (IAT) and to raise the octane. The best systems are progressive types and start injecting at a lower rate at low boost and progressively increase the amount of the injection as your boost increases. Progressive systems cost about $400 to $700 (not including installation).

 

Cool, so it does inject the alky/meth along with the gasoline injection.

that's all i really wanted to know. thanx man

 

I can keep up with the "how to clean windows thread" but this reply is a classic example of why this Forum is so great. Now I need to get out my car encyclopedia to figure out what he just said.....
