Wow, I thought this dyno was with the 8 psi pulley and the timing retarded 1 degree/psi.
Are you gonna dyno with this setup also? ( the setup I ordered )

i'm guessing that the time in fastvteccl's avator is scalberts time on a blown launch..maybe...
nice work steve, start workin on the internals and get some traction, u def got the power for low 12's

As for timing, no retard was needed. We'll have to see how the CA 91 octane issue works out before making a final decision. I would start with 1 degree per 2 PSI though.

That said, 25 - 30 WHP would probably be seen if the cut-out were open and 8 PSI boost was run. Unfortunately, this is not an entirely as simple thing to get more boost as it is to flip a switch and open the cut-out.
More research will need to be done.

Scalbert, I have comptech headers and the rest is stock , haven't been able to justify putting down $1k for the b-pipe and axlebacks yet. If there is no detnation no timing changes are needed? Just trying to understand everything. Your right though all we can get at the pumps here in California is 91 octane, kinda strange since there are more than half a dozen refineries in the Los Angeles area.
Just curious Steve, would an intercooler be able to pull double duty for a super charger and turbo charger?

I assume independantly and not concurrently (although that could be done). But yes, this same manifold/intercooler could be used on a turbo application.

The more I think about it the more I am considering an exhuast and brining the boost back up. That 400 WHP goal is too close not to try.
How is the drone with the Comptech cat back system?? Or, does anyone know the pipe size on the GReddy cat back??

One more thing, I think I am going to put a large reservior in the trunk, maybe a 5 gallon fuel cell, and see what the difference is. That should keep heat soak to a minimum and make it very easy to add ice.

The droan is definitely noticable when you are on the highway Steve. It was a big difference from the stock exhaust. If you are in 4th, 5th, or 6th gear around 2k RPM you'll hear it for sure. I bought the quiet tips but haven't put them in yet, people I asked said it will make a difference, but I'd lose 2-3 whp. Not really worried about the power loss because I could take them off easily at the track.
Ask mattg about the GReddy system. He has had it for a while.

I need to know the pipe diameter as Greddy's site is not cooperating (ASP SQL Server errors). But from what I remember, they don't show details anyway.

I have decided to run a larger, rear mounted reservoir (in the trunk) along with a custom radiator. This may not give power but should help to keep from losing it when how out. Plus, it will make it much easier to cool the system down if needed

And I really thought I was done...
After talking with my father-in-law he made a statement that for me now to not get an exhaust is like prepping a car and not painting it. :o
So I will go ahead and get an exhaust system. I went out and looked at how the pulley system could be changed to run just a bit more boost, and I found a solution. So I should be able to get rid of some of the back pressure, and run a bit more boost. I want to shoot for about 8 - 9 PSI again with the exhaust with the mean closer to 8.5 PSI.
That, under the similar conditions, should neat me over 280 WHP. Cooler weather and a few electronic tricks may be able to net me 400+ WHP as that is a new goal. I know where I stand right now so that goal is within reach.

Matt has had Comptech, HKS, and now the GReddy. He said the GReddy is by far the best in his opinion... although I don't think he had the CT with the B-pipe, just axle backs.

Question Steve: If the j32 is putting out 445 HP are you losing 75-80 through the drive train and netting 369? I've only been figuring about 25 for the manuals and about 51 for the autos. Is this correct?
Never the less the 369 is awesome and very encouraging to see. With the same setup would you expect the 5AT to be in the 345 range?
This is excellent!!

no drone steve. the exhaust is very subtle at highway speeds. it's only loud while the car is warming up and when you goose it at low rpm.

Oh i thought I remembered seeing you say that when you got the EVOs put on that they were the best because you have had all three. Must have been someone else.

I personally love the sound of my comptech mufflers .. they do drone on the highway a bit but I've used the quiet tips and it takes it back to the stock sound .. so you could always run them and then take them out on dyno or at the track .. plus I think the size and tip diameter and overall look of them are perfect on the CL

I dunno, I'm now re-thinking this whole thing.
What I would love to do is find someone local, install the exhaust real quick and see what the boost does. If it drops some I know it is flowing better and I can see if the sound is acceptable. But then again, I may just leave it alone.
I can always get another pulley for track use, a 3.0SC and run race fuel, when the cut-out is opened. I just now need to figure out how to mount the pulley as I hit a mechanical limit.

Oh also, what a difference a year makes. Below is my first dyno with the blower and is when I determined something was wrong. It turned out to being the FPR which was replaced under warranty by Comptech.
264WHP/239WTQ Pull
A far cry from now with 105 more WHP and 71 WTQ. Needless to say, you can really feel the difference.

I couldn't find your tread about the plug and play harness. Do you have a program for timing retard under boost and support 310cc injectors? If so I am ready to buy emanage, plug and play harness, pulleys(alternator and supercharge) and etc from you. I decided to keep my CL-S. Thanks.

Great Job Steve
Hey Steve
Those numbers are impressive I was wondering if you could point me into the right direction on getting those types of numbers in a J32 A1 motor for my cl. I have been contemplating purchasing the comptech kit, but I would like to see more power in my motor. Your Dyno numbers were just too impressive to ignore. Please advise me on what I should do and where I can purchase these modifications from.
Very respectfully
Benjamin Kim

I haven't really looked at the J32A1 engine and manifold to see what could be done. There are some inherent limitations in the amount of boost that would need to be run make that power on the 5AT. The blower really can't make that amount of boost without turning it too fast.
However, I could see potentially making in the 320 WHP range with the J32A1 with the blower.
But if 350+WHP is your goal I would look into making a custom turbo kit.
