Shift-S3ctor Airstrip Attack with Mike's single turbo LSx FD 11/10/12

I was also at the event. I saw mike pulling his car off, making couple passes then tunning and changing tires psi etc. love your car

My Holley boost controller was not working all day Saturday.  Sunday I put on a manual boost controller so I could run faster times and it worked. I gave out a lot of rides in the car Saturday and Sunday. So Mr Cunningham I have nothing to hide on the car. Next time ask me and I will give you a ride and you can hold the laptop. This setup has never seen the dyno. I got the car running a few days before the event and tuned it at shift sector.

While Ryne Cunningham was very vocal about your setup, this is not him. I am just a fellow racer that was at this event and found this thread so I wanted to clear the air a bit.

Good, sounded like Ryan. Next event introduce yourself and I will give you a ride. Last event I still have 200 more hp to use but I need to be able to put it to the ground. This is why I need to get my electronic boost controller working so I can run 15 psi up top. No reason for anyone to be mad. Allways faster cars at events. My car went 196mph in the mile before the turbo was added. So they do not need a lot of power to go fast.

I will gladly introduce myself and will also be happy to video tape exactly how the car performs at 4psi. It's not that you were faster, that's not what anyone really cares about it's that you are falsely portraying your car as something it's not. That is insulating to everyone's intelligence especially to those who are familiar with the LS platform.

Fine, I'm not sure I see what you're getting at... All I'm saying is, you can't compare just the PSI, it's not the best indicator of anything unless taken with other variables. I'm not sure if you guys are doing that, but it seems like maybe... You can't just like compare (for example) just the PSI of a Evo and some turbo LSx car, as some indicator of performance, it doesn't tell you much by itself.

You are absolutely correct! There are many variables to consider and that's why I am saying there's no way that car should have performed in that manner on 4psi. More like 15+. I have seen very similar builds and in order to be as fast as this car was, they had substantially higher boost levels.  When I said more like 24psi it was exaggerated but not by a whole lot. I personally think the last run on this car would have been around the 17 or 18psi range, that's based on all my experience around the LS platforms.

Okay but you seem to leaving something largely out of the equation - the turbo itself. The massflow, air density, the air temperature... Pressure ratios..

If i recall it was a pt-88 so no im not leaving it out of the equation.

Gts76. New turbo is a pt8847

Okay well you didn't say as much in your synopsis...

Self Affliction-  You are responding to a thread from November 2012; however are arguing about the race that happened in Spring 2013.

If the engine makes 500rwhp/450rwtq all motor and you add 4psi its around 625rwhp/600rwtq.  At 1 bar (14.7psi) it should make around 1000rwhp/just under 1000rwtq.

425rwhp n/a FD's run 126-128mph in the 1/4 with under 400rwtq
450rwhp FD will do low 130's
500rwhp mid 130's
550rwhp high 130's (enuf to run a 9 second pass)
600rwhp low 140's with 550rwtq

So with 625rwhp/600rwtq Mike's car should run a mid 9.   His turbo can make 350rwhp+ more than that at full tilt.
That is 170mph+ in the 1/4.

The RX-7 has a small frontal area.... but similar aero .cd to the cars at the event.  The frontal area is what is allowing him to kick butt above 140mph because he simply needs less power to do it.   My car did it also... above 140mph I would reel in the higher HP cars albeit me with around 550-575rwhp and they had low/mid 600rwhp (supercharged V8 M3's).  I also had a widebody kit and massive tires on it.

If someone wants to be the fastest at the 1/2 mile and 1 Mile shootout events it isn't about having a 2000hp twin turbo Corvette with nitrous like LMR.... or a 1400awhp GTR..... it would be about having the smallest frontal area car with good aero and similar power.  Frontal area is more critical than aero .cd rating.  Traction is also key.

That is how Bill Warner increased his top speed big time with his turbo Hayabusa..... until he died this year.  http://thekneeslider.com/bill-warner-rides-his-hayabusa-to-311-945-mph/    does this bodywork look like a stock Hayabusa?

10 psi on my last run 193.5mph. I turned it up for the TT ford gt. This motor has never seen a dyno but my last ls3 made max power at 14psi with 23* timing.  People forget that the rx7 does not need that much power to go fast.

I honestly don't even know why you are still talking.  Mike already said it goes low 170 at 4psi and was at 10 psi for the 193 mph run.

Didn't even see that this post is from last years event. Last year car had a different motor and I was using Fast efi. This year I put in a new motor and Holley efi. Not sure what event you are talking about.

Lots of bench racing in here

Yep.  Psi,dyno, bench racing doesn't win races. I kind of like not using the dyno anymore to tune my car. Now I just say I don't know what it makes.

Hahaha you're doing this internet thing ALL WRONG!

Can't wait to shake it up at these airstrip events this coming season.

Will be fun to have more rx7's at the airstrip. Make sure you have video of your boost gauge so people don't think you are running 40psi.
