Last year my best street tire pass was a 11.72@134mph with no boost control and the car was gutted making about 520ish whp on a stock sleeve motor...

This year its a whole motor, and ended up making 659whp/417tq @ 25psi on E85, it was out of fuel there on the dyno.. funny thing is on the street its out of fuel @ 23psi....


Tire pressure @ 17psi

First pass:

60ft: 2.159
1/8 : 8.143@104.25mph
1/4 : 11.932@131.77

Ran wastegate (10psi) in 1st/2nd gear, 3rd and 4th were 15psi

I always free rev and slip the clutch hard in 1st, normally only give it half throttle then shift, 2nd dead hooked same with 3rd and 4th...

2nd pass:

60ft: 2.101
1/8 : 7.950@105.91
1/4 : 11.663@134.10

Wastegate 1st/2nd, 3rd/4th 17psi

Same launch as before, banged 2nd hard and spun a little bit.. 3rd was borderline spinning, 4th hooked...

3rd pass:

60ft: 2.060
1/8 : 7.885@103.29
1/4 : 11.571@137.48

Wastegate 1st/2nd, 17psi in 3rd and 20psi in 4th...

It spun hard in 2nd gear (hence mph down in the 1/8th), 3rd hooked and so did 4th...

After that pass i got the boot, and the special letter saying i cant race this car again until i have a license/cage ECT... I am pretty sure the car could do 140mph on street tires, i did 138 a few weeks ago but was only a 12.0.. 20psi in 4th held fine and i think it could do more....

84mm stock sleeves???

Gold DA9

bauergold

Pretty sure he's sleeved now.

Nice times!
140mph on street tires would be legit!

BMo Tuning

Your street tire times are

Nitto might want to contact you for some sponsorship lol

gringotegra

No....



Thanks guys.. I am pretty sure i could get it to run a 11.49 or faster but now that im banned until i get a cage/license ETC i can't even run the car anymore lol


Imagine pulling up to the line on street tires in a full fire sute, gloves, window net and cage lol...

Terrible One

sick times! what's your tranny setup?

gringotegra

Gsr tranny with an LS final drive and an ITR 5th gear


The ls final is good for 4 more mph in 4th gear..

Badass! very impressive ..

ROMEO856

nice, i will be trying street tires on one of our cars aswell soon... hoping to run 11.5s as well but i know it aint no walk in the park but im ready for it

gringotegra

The launch is the hardest part... i cant explain how to do it but it's a technique ive learned over many passes...

gringotegra

This video is from last year but i basically slip the clutch so the car does not bog in 1st gear... This pass the car wheelhopped a bit so thats why it was hoppin all over lol

shasky_twin_turbo

congrats gringo nice to hear u having fun with ur car... stop spinning tires and put some slicks, or u are trying to reach the 10s at street tires...
when u talk about street tires specifically wich one u mean????
good luck and give me a call anytime. 829-641-7169..

Sickteg24

a little off topic but how do you like those FIC 2150's?

gringotegra

Whats up Shasky!! Yah man im just having fun thats all lol..

I went 10.48@145 a few weeks ago, the problem with running slicks at this track is i get booted right away... So at least on street tires i was able to do some passes and have fun! There is just something cool about driving to the track and just running without having to bolt up slicks!

These street tires are Nitto Neo Gens 205/50/15.. They are just a standard summer tire id say.. They are not an R comp tire, i think the treadware is 280, and they have a soft sidewall so they air down very well!

Im gunna give you a call tonight! Been a while since we have talked!

gringotegra

Love them, idles right at 1000rpm with no idle motor lol

Gold DA9

no idle motor... no idle air control valve?

gringotegra

No its unpluged.. It was acting up so we un pluged it and the damn thing idles perfect after its warmed up

T4eg

gringotegra

Yah i know man i know, I think it can go faster but i cant go again till next year anyway !!
