Default Short/Long Term Goal Advice - 2002 SS

Hello,

I couldn't find a better place for this thread than the "newbie tech" page, so here goes..

I recently picked up an extremely clean and well-cared for 2002 SS M6 in LA for way less than the owner had in it. I have been working on these LS cars for nearly a decade (friends and friends of friends), but never owned one myself. I finally decided to pull the trigger and went on a search for one. I was lucky enough to find this one close enough to me (350ish miles) with nearly everything done to it that I always wanted to do if I built one myself. So, I flew to LA the following week and drove it home (what a runner!). My signature lists the main modifications on the car, but aside from those, what a clean car! The interior is typical (ripped drivers seat and cracked dash), but other than that, perfect! Since I've had it, I switched to 5W-40 in the engine and replaced the DEX III in the tranny for some peace of mind.

Short term with the current HP/TQ setup (415/389), I'd really just like to upgrade to a Tick MC while I wait on the funds to upgrade the 10 bolt and maybe try to squeeze a little more power out of the current setup. Any ideas on how to go about doing that without going broke for a 102 or other bank breaker?

Long term, or after the LS1 gives up, the idea in my mind has always been a forged 370 with a P1SC Procharger. All I've ever wanted in a weekend cruiser/occasional track car is somewhere between 500-600whp (along with the Procharger whine )

As previously stated, I mainly posted this to draw some advice and insight as to the current state of my car and ways to draw everything I can from the current setup. I plan to hold on to it as long as possible, so we'll see what develops.

Thanks for your time!

Do you know what your current compression ratio is and whether or not your heads have been milled? Porting the heads and increasing the compression are what comes to mind in order to squeeze out some more power. How do you feel about n2o?

If feasable ditching the 10 bolt is good regardless or the present or future

The receipt from the machine shop indicates they surfaced the heads .030. I can't find a receipt for the head gasket, so not sure on it's thickness. Not sure if we can compute a CR without the thickness of the head gasket in the equation.

I've made only one N20 pass in my life (friends Eclipse), so I'm not too sure if I want to go that route. Is there a "safe shot" that you can shoot to limit the potential damage to the bearings and such?

I stand corrected. The kit used was https://www.summitracing.com/parts/n...9217/overview/

Compressed Thickness (in): 0.051 in.

Any idea on the CR based on the known info?

Agreed. I just want to be able to do it right with either a Moser or Strange setup.

A 102 Fast isnt gonna help you much. I'd say the best bet is to get some aftermarket heads. You don't have a whole hell of a lot more to do to max your combo out. Really good builds get like 450rwhp, so your most of the way there.

Speed Engineering Headers.

True Dual Exhaust

A different, more aggressive cam.

And heads, like I said.

I figured as much. Not looking for a huge jump in power before I do the boosted setup (415 has a good WOT feel in the drivers seat), but wherever I can squeeze some power out on the cheap, I'll explore options.

Here's links to tonight's two dyno pulls. Came up with 389 whp with the drag radials...right in line with the 415 whp previously reported with street tires.

The 389 hp vs 415 hp was two different dynos correct?

Correct. It was originally done in CA (without DR's) when the previous owner completed the H/C/I setup, and this was tonight in AZ (with DR's).

Most of the guys getting dyno results claimed the numbers from this dyno were lower than normal for their cars...who knows...

Any comments on the CR I came up with a few days ago?

Running drag radials on the dyno would not make you lose 26rwhp

Everyone who ran their car on that particular dyno was coming up with much lower numbers than normal for their cars, so I just blame it on that dyno.
