VMAX ZL1/LSA 87mm TB Test Results - 31+ RWHP w/o Tuning - JDP Motorsports

[white ZL1]

So with the 125 you guys gained using the BTR stage 3 cam and 50rwhp on this, you're telling me that an A6 ZL1 would see 625rwhp on stock boost?

Something's off here Tyler.

Well looks like I'll be ordering a TB soon

Hello Jordan,

Bravo for your efforts.

I certainly don't want to rain on your parade but We have to stand back and really analyze the Data.

First We know for sure that ZL-1 Auto cars put down 465-470 RWHP pretty consistently across the board.

Your Base line numbers are very low which indicates to me a Hot supercharger IAT2

Without Logging IAT and IAT2 ECT Timing, Knock Retard, LTFTs Manifold pressure, fuel pressure, AFR etc. and including these in your reports, the Test is a big waste of time and misleading to consumers.

We have noted significant differences in Power levels on these cars on our dyno all Primarily controlled by IAT which has the largest affect on final Timing value.

So if you want to do real back to back testing you have to first Monitor all your vitals, Then stablilize them to a constant starting point.

Your final numbers have been noted on many ZL-1 Autos.

I only post this in a effort to help you gather more accurate data.

Ted.

There is a lot more to it than that... When you start adding cams, headers, intakes the boost drops. We then add the boost back and you end up with the results..

Ted,

I agree with you so far as logging everything goes. This particular test was done on the same day within 30 minutes. The car actually sat for a longer period of time before the first OEM Test to the VMAX test and ambient went up 4 degrees. We've since seen an average of 20 RWHP which is inline with testing that others have done and I have all of the data; I just haven't had the time to post it. It was done on the same car and we also logged it with the CAI intake.

We have another ZL1 coming in for various things; I'll strap it down and log it before and after replicating the conditions. This has been a great modification for the money and we include them in most of our packages.

Kind regards,

I completely understand that. But that's not what has been posted.

This is with bolt-ons and 28% lower pulley before and after the cam

With nothing more than the cam swap you gained 125rwhp?

We test every product we offer and share our results. You can take it for what it's worth but we'll be doing another JDP ZL-800 Track Spec (Road Course) Build very soon using the BTR Stage III PD camshaft in our package. Please feel free to call, email or PM me anytime with questions..

And another 45-55rwhp for a Rotofab and vMax.

And this isn't misleading to the average enthusiast?

I can understand your point. It does

And I'm not trying to pick on the JDP guys. They support this forum and I've made a few small purchases from them in the past and wouldn't have a problem doing so in the future.

I have this combo on an otherwise stock auto and I gained 33 HP at the wheels.

I posted the difference between full bolt-ons and then adding the cam and we gained 125 WHP over what it made before. I never said it would gain 125 WHP with a cam swap on an otherwise stock engine. I believe we had a misinterpreted understanding.
