ive been reading through all of this and im wondering if a lot of these times are acheived on nitrous? and what kind of rwhp's are getting put down for thes mid-low 11 runs. if those stock twins are getting those times with no n2o thats impressive.

Ive also been trying to find average 1/4 times for t-78 turbo setups with the works done (500 flywheel hp, so probly cars with about 450rwhp) since not many here seem to be doing singles, and if those are sprayed or not as well.

 

Very few RX7s are spraying. I ran my 11.7 on stock twins and stock ports with no spray. I am currently making a little over 400rwhp and have made several 11.2 second passes.

450rwhp should put you into the mid to high 10's assuming you have the right tires, diff, and you can drive

 

thanks for the reply, those answers are what I was guessing.

im sending you a pm fast if you could reply would be appreciated.

 

i went a little quicker on weekend also with an 9.61@145mph and an 1.44 60 foot time and an 117mph @ 1/2 track testing for qld jamboree over here next month...used c16 race fuel , no gas and m/t 8.5 inch slick untubbed.....hope to go quicker again with some more track time...cheers

 

Did my best 1/4mile almost 2 weeks ago. With some serrous gearing problems.

60' 1.790
1/4 12.533 (186.2Km/h 116,37mph)

This was done at 13psi of boost on a Trust TD06H-25G turbo and with Bridgestone RE540S street slicks with 20 psi of air.

Could have done a 11 sek if it would have been easier to get it into gears.
It was tough to get into all gears.

 

your 406 hp doesn't match up to your 126 mph trap speed. How much does your car weigh?

 

Car weighed 3020lbs with me that night.

 

still seems like a high trap for only 406

 

Would you like the video and a dyno graph? Or better yet hop on a plane, come down to Texas and you can see it happen for yourself

 

Here's the timeslip...

 

Tell me this, at about what rpm do you shift at?

 

Launch 5500 rpms
1st gear 7500 to 7800 rpms
2nd gear 7500 to 7800 rpms
3rd gear 7500 to 7800 rpms
4th gear cross the line at about 6000 rpms

I don't see how the hell you managed to pull that off. I just ran last night in SC and I have almost the same set up as you. Stock TMIC, stock turbo, streetported with intake and exhaust, 255lph pump with 850 secondaries and running 20psi. on 245/45 AVS ES100's. The first and only run of the night yielded a 2.25 60' (my best so far) and a 13.8 @102.3 (also best so far) Temp was about mid to low 70's (F). What am I doing wrong??

 

Have you noticed any mph "trap" loss when shifting at too high of rpm's? What kind of port do you have?

 

Stock ports...my trap speed slips a little when I shift at lower rpms.

 

Weird, my traps slip big time when I go mid 8K. I get excited and don't want to shift

 

I would have had a full run but ran into all sorts of personal problems.

Ran two 1.58 sixty foots and one 1.557 sixty foot.

My best 330 was a 4.707

 

new times today:

60' 2.111
1/8 8.741
mph 81.69
1/4 13.467
mph 105.44

stock turbo, stock TMIC, streetported with intake and exhaust.

 

Dam I can't find my ticket but on Oct. 31 2004.
I came in 3rd placed cause, I broke my dial in. Mind you it was my b-day and i went with my 88 GTU just to have fun. Would never thought the car would keep hidding the same numbers all time. My car has K&N filter and Racing Beat Header. Nothing else is done to it. My dial in was 15.49 and when I was racing for 2nd place, out of no wear, my rival and me was neck and neck that i could'nt let go not to break and My GTU ran an et 15.2. Man I went home with cash 2 trophies and a big smile cause the GTU runs great.

 

Nice i ran a 15.2 in my NA it feels great doesn't it? an NA that'll hang with a stock tii

 

don't have a reply but was just wondering, I have a 6 port 13B if I upgrade the ir filter to
a cone air filter, put on a racing beat full exuast, upgrade the stock coils to MSD coils put in a MSD box and street ported the engine how much hirses will I have and if you would know the quarter mile time? thanx
