So April 2019.... going on in gtr's Evolution....
Has anyone run both the wavetrack front and rear diffs on the dragstrip or roadcourse? how did they perform? All front and rear upgraded diff cars how have they been performing on the street/track?.
I have Both diffs installed on car. I have not run it on a road course with them. I have however driven them on the street for thousands of miles and made numerous 7 second passes at over 200MPH without issue.
Saw a post somewhere about shep having new gr6 upgrades....What are they? What else can be done to upgrade the gr6?
This may be old news, but the Dodson Billet front housing gives me peace of mind that I will not break the prop shaft input off and put trans fluid down in front of the rear tires. This is a concern in big horsepower applications. Also, Dodson is now making their own Synchros for the GR6
what are maxxed out Elite primes and pro 1700 kits making powerwise these days? i read somewhere a 58mm car ran like 7.5 or something.
Both AMS and Command have fast 58mm cars running in the 7.5X range at high 180s traps. Both cars are on methanol and very light. Daves car (AMS) won his class at Texas 2K and was in the 7.5x range on a 17" slick; not a 15".
Has anyone run the new t1 super atom weight brakes yet?
I have them on my car. the weight savings is astounding. since the are a carbon carbon setup they do need to be up to temp before any significant brake torque can be had. I notice about a half second delay between getting on the brakes and any significant brake torque. These are not street parts and should be run in conjunction with a chute.
Has anyone run a wider than x13 tire in the rear? I thought i read that T1 and ams had a solution for wider tires in the rear. or multiple cars were running larger tires. Did they mean height or width?
Ive run a 29.5"x13.5" tire in the rear at the last two events. It really changes the car. running 7.40s on a big tire feels less sketchy than running 7.60s did on my old 10.5W setup. HIGHLY recommended. I know that T1 has run a big tire, and I believe (don't quote me on it) they change the front diff ratio to correct wheel RPM for the differential tire rollout.
I am running the AMS big tire solution on my car which consists of a new set of drop gears in the transmission to correct for differential rollout. I am also running their new billet spindle which allows a more inboard shock location. This more inboard shock location allows for the wheel to come in towards the centerline of the car further. As a result, I can fit the "big tire" under my stock rear quarter panel with no hammering, cutting, fender flares etc.
anymore data updates on the topspeed manifold?
None from me, the cars I saw running it had teething issues unrelated to the manifold.
There was a posted update for they K.A.P.S awd control. Can anyone report on it? anyone running it?
Any guys with upgraded front clutches want to share how those and awd control has been performing on the street/track?
I have tighter front clutches. Im not sure how much to attribute this but I was able to cut a 1.21 60ft in a 3600+ pound car.
any cool new things coming out in the motec or syyvecs software?
Syvecs is using a GPS speed reference for traction control now. It seems to be working well for my car. my pig went 7.06@206 running it.
has anyone other than roberttttt rany the wisefab suspention setup? or brypar uprights?
If seen more than a few gtrs with a license plate exit tailpipe. Are they cutting out the trunk for this mod?
Whats going on in the world of tractive as far as the gtr? Anyone run tractives at Texas 2k? Have the setups been getting more dialed in?
Has anyone seen the gtr with the big motec screen? Whose is it?
