TEXAS SPEED New NA Stock Bottom-End Heads/Cam Record with 9.66!!!

Jon@Texas-Speed · 10-21-2009, 04:35 PM

Again, we made the long haul to Memphis for the LSX Shootout at Memphis Motorsports Park. We brought our naturally aspirated '98 Camaro with a stock 346c.i. short-block with heads/cam that held the previous heads/cam record of 9.82 @ 134 mph. The car was essentially unchanged other than the addition of a MadMan torque arm and manual rack. The motor received a new set of the NEW PRC 227cc small chamber aftermarket casting cylinder heads as well as a TSP prototype "MS-5" camshaft. After testing a couple different intake options we opted to go back with the ported FAST intake we ran to set the record in 2008.

The first pass on the car since last year and on the new setup went a 9.72 @ 134.8 mph with a 1.300 short time. The car was a little soft to the 60 ft compared to last year so we were hoping for better times to come. Saturday morning turned out to be our best pass of the weekend with no changes to the car. We ended up going 9.66 @ 131 mph again going 1.307 to the 60 ft mark. Unfortunately the wind was pretty crazy so the mph was down on that pass, but it picked the mph back up when the wind died down. Saturday night's pass went 136 mph but netted a slower ET with a 9.72 after peddling the car. With one shot left Sunday morning since we were figuring on breaking out of our index, we loosened the front end up trying to make the car leave better. The car ended up leaving with the front end up similar to last year. Jason had to lift for a split second to come down again. It ended up with a 9.75 @ 136 mph with a 1.45 60ft tripping the beams with the back tires! We were hoping for a high 9.5x pass but it wasn't meant to be for the time being. We'll probably have to head to Houston when the weather here in TX cools off for that kind of number.

All in all, it was a successful trip. Tuesday night it didn't look like we were even going to make the race since Trevor wasn't going to go due to a death in the family. Jason stepped up and drove the 14 hours there, drove the car, and drove back! As always, it was good to see old friends and meet new ones. Big thanks to Madman for helping dial the suspension in again. I hope to have pics from the race posted up later tonight or tomorrow sometime.

Feel free to post up and thoughts, questions, concerns...

Thanks!

Somehow I knew we were gonna go there . . . . . Congrats to you guys at Texas Speed I made a run at it on Monday but came up just short of your OLD record LOL. Is this a pump gas motor?

JRracing · 10-22-2009, 12:41 AM

Congrats guys. I to am wondering the race weight. The 1.30 60' is killer. That's were it is at!

jdiddyws6 · 10-22-2009, 10:53 AM

Glide, 5900 stall, lexan windows, 2800lbs

Jon@Texas-Speed · 10-22-2009, 11:58 AM

Thanks guys! I'm trying to get the pics uploaded shortly. We didn't get any vids of the car this year.

The car actually weighs closer to 2900 lbs this year with Jason driving. Car was 2860 last year with Trevor in the seat. We never rescaled the car for Jason.

It doesn't have a glide it actually has TH200 with a 5900 Stall.

We do run race gas in the car. It isn't a pump gas motor.

ONEBADWS6 · 10-22-2009, 12:10 PM

what kind of power does it make to the tire?

LS1 SPEED · 10-22-2009, 12:11 PM

congrats! The car look great and sounded wicked.

WS6TransAm01 · 10-22-2009, 12:17 PM

Big Time CONGRATS TEXAS SPEED.Shows what a stock cube motor can do.
What rpm are you shifting at?
Is the MS 5 a solid roller cam?
Thanks

Zero4488 · 10-22-2009, 02:54 PM

Awesome work guys....

Zero4488 · 10-22-2009, 02:55 PM

also you need any more test subjects for that MS-5?

-Joseph- · 10-23-2009, 12:42 AM

JFM, I think he was shifting it by 7200 and it crossed the traps at 7100. I regeared it after last years race (I think) to 4.10's from 4.30's.

This was the last pass of the weekend:

lemons12 · 10-23-2009, 12:47 AM

It pisses me off so bad I didn't get to see it run (one of the main reasons I went) and sucks also that I didn't get to check the setup a little bit longer.

For anyone curious this does not look as hacked up / gutted as a lot of cars I see at a much heavier race weight.

Congrats TSP!
