Ok, so I was tired of looking at Dean's tail lights (and soon to be Brandi's) so I decided to go forward with the new intake setup from ST Motorsports. I have run as fast as 10.77 @ 125.82 mph yet I am the slow one, go figure.
I wanted to see what difference the ST sheet metal supercharger intake, the black diamond throttle body, and the ST intake tube would make. Even though I have had my car dyno'd many times before, we decided to re-dyno everything in back to back tests to really see what difference this setup was worth.
All of the following dyno runs were made within 3 hours of each other. The first dyno run was made at 63 degrees where as the last dyno run was made at 58 degrees. NO TUNE CHANGES, NO PULLEY CHANGES, just the intake setup and thats it. All numbers are SAE. Uncorrected the numbers were actually higher.
First was to dyno the stock whipple system along with the stock throttle body. With this set up and the same exact tune, I ran a 11.32 @ 119 at Ca Speedway in October at FFW. With two baseline passes, the numbers that came back were as follows:
Run#1: 483.62rwhp / 456.70rwtq
Run#2: 484.49rwhp / 457.95rwtq
Now, one might say that is low for a whipple at 16psi. But that was exactly my point---because of the stock throttle body being the restriction, there was really no difference at all in power between the whipple at 13psi and at 16psi. (A few months ago I was running at 13psi with very similar numbers)
Next test was really just for me, as I wanted to see exactly what the numbers were with the BBK throttle body and stock whipple setup. With this setup, I ran a best 10.77 @ 125.82 mph at FAMOSO in November.
That dyno run came back at 511rwhp. So this throttle body on a whipple running 16psi, with no other changes, was worth 27rwhp. This in my opinion proved that the stock throttle body was indeed a big part of the restriction once you decide to go over 13psi on a twin screw supercharger.
Next up, Adam pulled off the stock setup and put on the sheet metal intake, the black diamond wide mouth throttle body (1600+cfm) and a larger intake tube which also runs outside the engine compartment (like the KB setup).
We ran three dyno runs with the following results:
Run #1: 576.90rwhp / 517.51rwtq +92rwhp over baseline
Run #2: 565.50rwhp / 519.28rwtq +81rwhp over baseline
Run #3: 571.43rwhp / 518.24rwtq +87rwhp over baseline
Remember, this is an auto to boot---so with a manual this car would be 600rwhp!
Since I have already ran a 10.77 @ 511 rwhp, I can't wait to get back to the track with 577rwhp---I am hoping for 10.4X's!
Here are some pictures which include:
1) the stock whipple intake setup with my BBK throttle body (511rwhp)
2) the ST Motorsports intake setup (577rwhp)
3) picture of the three different throttle bodies
4) picture comparing the stock whipple intake vs the sheet metal intake
5) dyno graph
Since I now will easily be able to run the PSCA 10.60 class, I won't even need my Innovative 10% overdrive crank pulley---anyone want the buy that from me? I also now have a BBK throttle body for sale! PM me.
I will upload a video of all of the dyno runs tomorrow and post the link, its uploading now but will take a while.
So Dean and Brandi---what ya gonna do now??? I know, your going to be buying me a slurpee after I kick your ass at the track.
By the way, I saw two 3.4 whipple superchargers at ST today---wonder who is getting those......
