hey jeff or any other explain whats going on here ? maybe i missed something but both cars are tuned on 93 octane and running 20psi. but one turbo is a 30R and the other a 35R and both are running a .85 a/r.

i think i understand why the 30R is making more power, but i wanna confirm if .2L is really that much more displacement. i would think that the compressor efficency would come into play somewhere here

 

The car running the gt30r has a ported head, more displacement and larger cams. Both cars are trapping similar mph levels, but at very different weights (30r is much heavier by around 400 lbs or so). The tuner 1 skunk2 cams make a huge difference in power output from what i have found.

 

GT30R car looks like it has a 84mm bore, cams, ported head and a larger throttle body.

GT35R looks like it has a stock head, stockish bore, stock cam, stock TB

I'd say probably the head and the bore are the two biggest differences.

Edit: Haha, the man himself speaks before me.

ahh ok didnt see the ported head head and weight parts. but thanks for the answer

 

The 30r car trapped 133mph at 27xx lbs. The 35r car trapped 133mph at 23xx lbs, but running 23" slicks and hitting limiter in the middle of 4th gear through the traps so probably would have went 135-137mph range.

I just recently tuned a 35r car on pump gas with a 2.0 liter, tuner 1 cams, etc and made 550whp at 22psi and ran a 10.63 @ 141mph on 93 octane!!!

Cams make a huge difference. I have seen around 20-30 whp gains with the tuner 1 cams over the ctr/itr cams at the same boost level. Also, the difference between a 81mm to 84mm bore and 87mm to 89mm stroke is worth an additional 30-40whp in most cases with everything kept similar in parts.

 

i plan on keeping my motor 82mm because im going to run wiseco pistons and the stock 89mm crank. as for cams i have a type-r head so i guess ill pick up the skunk2 tuners 1's and dyno both when the cars ready. oh and i plan on keeping all the seats and a/c if i can florida gets hot and a/c is must

 

WOW! What kind of timing are these set-ups running at that boost level and 93 octane?

Would like to know as well. Champlsinteg your #'s are very good for that turbo, same as mine. Can I ask more about the setup?

 

champLS and root if you dont mind can you post your torque numbers

Notice the huge jump in torque from the 2 graphs!

PM me

 

oh thats very nice now try on C16 but thats a good torque line. depending on your suspension and car weight have fun hitting high 10's

I'm raising the boost and tuning on c16 next time. I have not weighed the car but its probably over 2700 with me in it. I'm 225! LOL! I should be able to do it with that power with a better 60ft.

lol thats for sure. get those 60ft times to 1.6 also what size slick you running

im 126lbs. so anything pulling me is barely working to do so
