Basically you can rebuild the entire camaro or mustang (minus the engine), and for the 370 you can....upgrade the stock brakes, use adjustable arms, and swap for HR heads.

That's Because otherwise the z would win too much...can't have that happen now ...

The Z is allowed a lot of upgrades in the GS class.... Being the smallest NA engine.
We are also the lightest car...which helps big time when the tracks get hot.
Doran Racing really began this project after our first race at Barber after we got crushed by a Mustang in turn 1 of the race.
Engine wise : we have removed all the oem wiring and electronics and run the Grand am spec Bosch Motorsport ecu.
We run our own intake and are allowed a full exhaust system. Grand am has approved camshafts as well and a dry sump system.
Suspension wise we are still working on it to make it even better.....always

Remember the mustang and Camaro are penalized heavily with weight and power restrictions. They also have to run same size tires as the Z at much higher weight. Organizers have been equalizing all the cars. These restrictions aren't well published to general public.

Also the motors in 370s that run GS are more than HR headed VQ motors typically. They have very expensive engine management systems, racing brake systems, racing cooling systems, suspension upgrades, rear dif and LSD upgrades, oiling upgrades, etc. yep pretty much completely rebuilt car. Don't forget Doran started with a $150k racing car version of 370z and still had to make major mods to be competitive.

Actually they all have 275 front and rear tires as we are only allowed 245 front and 275 rear.
They make about 120+ lbs of tq to the wheels more than us.
Everyone is allowed differential upgrades and suspension upgrades... Sways / bushings etc
Brakes : we are allowed going up 5% on front rotor diameter from the oem 370z rotor and to upgrade to any alum 2 piece 4 piston front caliper. We "upgrade" to the oem
350Z rear caliper.

Yeah but for all practical purposes you guys are on same width tires. They get an inch more up front on car that is heavily front weight biased. They have same width rear with 120 ft lbs more torque! Ouch!

gomer_110 · 10-16-2012, 09:32 PM

Dwnshift, any word on whether you guys will be at the Daytona race in Jan.?

Dwnshift · 10-16-2012, 10:52 PM

Yes their 120lbs more of tq is a real disadvantage for them.

We shall see... we are working on a couple things that could make it really interesting.

.....Double yawn. Hope this is more than all big talk we have heard all season. Man you guys should consider politics! I want to see product developments and results. We haven't seen much of anything yet? Don't get me wrong I think 370z is winning platform just not sure Doran team is maximizing it yet? Please prove me wrong! That would make me very happy but I lost faith in your efforts early in the season. Hope the super secret mods do something to attain actual results next year! ... Unfortunately I doubt we will see much more than mixed results and hey we were gaining etc. racing is all about winning. No wins no glory.

I hate to say it but seems like you guys have driving talent why not go with 997 4 liter Porsche? With fast drivers that car has better chance of winning?

dastaco · 10-17-2012, 02:20 AM

I see Shamu is back to his forum trolling ways. Thank god someone has the stones to tell the professionals how they should be racing...:screwy:
