stockchassis second gen. non-turbo runs 10.6@130mph
 

This is an interesting car. friend and customer Trevor Durham has a non-turbo second gen Rx7. This car is running a stock chassis with a stock turbo II differencial. car is basically a second gen Rx7 that has been on a diet.( no interior and plastic windows) but still a somewhat heavy car. Engine and nitrous oxide is being done and tuned by me. Second gen. runs a very impressive 10.63@ 130 mph non-turbo. what is interesting about this car is the stock rear and stock axels. he hasn't broken 1 yet. this 10.63 run was more like a 10.20 run, a few driver erros caused a slower E.T. what is also interesting is that this non-turbo stock chassis second gen Rx7 has more in it!! more like a 9.9 run and all on a $45.00 dollar nitrous oxide fill. got nitrous? :-) I have a few video runs on my phone but to crappy to post. we will be going out soon to test again and i'll get some good video footage. goal for this stock chassis second gen. Rx7 is 9.9@135mph.

I'll keep the site up to date.

im afraid of nos haha

Pictures please!!

Thats definitely one of the best times I've ever heard on an N/A, yes please pics and more info on the engine?

Holy crap. Pics and vids please!

i am stunned it managed that ET with such a horrid 60'

yes, when you see a time slip like this, you could do the math and see the car has tons more in it..

How much of a diet? Weight with driver?

i'm not sure. i'll get some numbers of the weight soon. i could tell you the driver is about 250lbs.

Cool thanks. I have an idea of where it might be but assuming gets no one anywhere. I'm always interested in what other folks do to achieve a certain weight and compare notes. My 10th AE is pretty light somewhere in the 21xx range. At least thats where i guesstimate it to be (old weight - weight of stuff removed = new estimated weight). Thanks for the numbers in advance. Lets see that 9.xxx!!!

Shoot.. I have been cutting 1.50 60 foots and 10 sec slips for about a year now on a stock rear and axels. Had the car for 5 years now and havent replaced a single one... I just think Mazda made some pretty good stuff for the rear end.

Rat

went to the track to do some more testing. driver and owner Trevor is having a real hard time getting the launch correct. we were able to get 1 run before it started to rain.

details of that 1 run..

10.5@132.79mph

Rx7 improves 1 tenth and 2 mph but car has tons more in it.. taking baby steps here, but I gotta be patient with the rookie driver..

what tires he running?

MT 15x26x10 DOT drag radials
