    • BoostAddict member drives his GTR to drag strip, lowers tire pressure, run 8's, raises tire pressure, drives home

      I figured this might interest some of you. Florida had some decent spring weather Thursday night (+1200 DA but it felt nicer than that), so I went to Test and Tune at Bradenton Motorsports Park. I drove an hour down to the track, dropped the tire pressure from 20 psi down to 14 psi, got in line (10 cars) and knocked out a new PB by a long shot, 8.622 @ 161.43!


      I was ecstatic. No burn out. 4400 RPM launch targeting 1.4 bar BOTL on the Ecutek app (though I doubt I built much boost since I didn't stay at 4400 RPM very long). I decided to call it a night and drove home after airing back up to 20 psi. Tires are Mickey Thompson Street R on 18" wheels (29" tall) in the rear with a matching height street tire on a 19" wheel up front.

        Vbox from this pass. 60-130 and 100-150 on this pass were both 3.5 seconds. Best 60-130 is 3.3 and best 100-150 is 3.2 in negative DA conditions.

        Thanks!

        With 2 kids and a law practice, it's hard to find time. My oldest will be 5 in July, and I'll start teaching her around then, so I'm sure that'll motivate me to play more.

        Edited for formatting and promote to the front page.

        Simply phenomenal. I'm a bit jealous.

        Not a huge GTR fan but it's impossible to not respect this. Literally go to the track, run 8's, drive home.

        It’s a testament to the platform, I’m not sure how many other cars can be built to run 8’s and still be completely streetable.
        However speaking of built, Jesus Christ that’s a full build. 4.4 built stroker with all the goodies. $$$$

        Thanks for the promotion to the front page.

        Yes, the platform is pretty incredible. And yes, other than me using Jack's rather than Shep, pretty much everything on the build is far from the "budget" option, which is laughable considering my Jack's transmission probably still has $35k plus invested in it but would have been $45k+ with Shep.

        The platform development has gotten even better since I decided to do the stroker 2 years ago. If I were building the car now, I would have kept stock displacement and used one of the many new "stock frame" turbo upgrades which spool equal to or better than my turbos do with the stroker and make virtually the same power.

        1k whp pump gas GTR is called ultimate street car, many years back...I think only thing R36 needs to be is smaller and 400lbs lighter and improved efficiency with 48V carrying auxiliaries. R36 would make a strong comeback and keep up for many years to come.

        The Nissan GTR is truly the King of the Streets

        But you could also do the stroker with those new turbos for even better spool and power?

        They'll screw it up like the new NSX.

        Cicio from TSM tried it and the tiny stock frame turbine housing created too much back pressure for a 4.4 and actually made less power. They have built numerous 3.8 liter cars with their ďElite PlusĒ turbos that have gone mid 8s as well for less money.

        If I do anything further to the car, it will be the ETS Pro1700 kit based on gen 2 3582s which would be good for traps in the mid-high 170s and probably a 7.9 if I were willing to do a small rear brake and a 15Ē wheel. With a similar 60í and another 300-400 whp that pulls cleanly to the mid-high 8,000 RPMs, the car would probably go 8.2 on the same tires.

        Incredible.

        No reason to mess with it though unless you're bored...

        interested to know if you could do all over again with the mods available today, how would you do it for an 8sec gtr?

        Keep it a 3.8 and do heads and cams. Billet crank starts to become more necessary approaching 1300 wheel.

        Skip the ams carbon. Itís pretty and Iím sure it makes some power, but not necessary with these setups.

        Iíd let Jackís build be a trans again. It has performed well.

        Turbos would be Elite Plus by TSM or BoostLogic equivalents.

        most of the rest of the build would stay same as far as fuel requirements and such.

        Starting from a stock car, itís still $100k. There are several nice examples of well modded cars that can be had for very low 100s. Another nice car sold this week for $100k that has gone 8s.

        Not sure if I'm understanding but the build cost is not $100k? You're saying $100k total after buying a stock example?

        Yep. When I got the GTR, I came out of a AA Supercharged E46 M3. I was going to leave the GTR stock. I swore I wouldn’t mod it. A 9 second GTR was a big deal in mid 2012 when I got mine. I think Alpha Omega had just gone 8s but that was a race car and I’m sure drove like crap. I saw videos of a GTR running E85 beating a HC C6 Z06 and I was impressed. I did boltons and loved it. My local buddy built his car and I swore I’d never do that. Jack’s Trans began doing competitively priced builds and I shipped my car to Colorado. There were some issues mostly not their fault and car got sorted and made 915 wheel and went 9.18 @ 150. They were stock frame 6758 EFRs and spooled instantly. I couldn’t leave it alone and did an ETS kit with gen 1 3576s and my motor wasn’t super happy so I did the 4.4. And there are more than a few GTRs around the country that are much faster than mine and are driven way harder and more often than mine. Still, a 3.3 60-130 is pretty insane for a street car especially when you consider how “fast” a 720s is and it did 5.3 60-130.

        Iím saying it would cost around $100k to build a reliable 8 second GTR parts and labor not including cost of the car.
