• Horsepower Freaks Stage 5 turbo E46 M3 making over 1000 horsepower takes on a turbo Acura Integra GSR... and loses

      We were extremely impressed when just a couple days ago we saw the dyno numbers posted for the Horsepower Freaks Stage 5 E46 M3 turbo. There is not much a car making over 1,000 horsepower needs to worry about. An Acura Integra would likely be the least of the worries of a vehicle that powerful but guess again. BimmerBoost member @gringotegra's turbo Integra GSR definitely impressed us and was surprisingly fast vs. stout competition. This is a case of power to weight as the Integra at around 2500 pounds is almost 1 1/2 ton lighter than the E46 M3 it was racing. That definitely helps when the Acura is making around 300 wheel horsepower less.

      The video was very well made and the camera work by HPF is to be applauded. Additionally, it was nice to see this race take place after @gringotegra would (the proper word likely being incite) reactions out of HPF owners. The Integra also seemed to get out of it a bit early as we feel if the race went longer the more it would favor the M3. They will be racing again after some tweaks by Horsepower Freaks to the setup on the M3. Specs on the Integra below and more can be seen in the thread on the car here.

        Quite close. Informative video. Weight and also to some degree aerodynamics matters.

        Anyone else starting to think the m3 doesnt make 1000whp or has the $#@!tiest power band in the world.That honda is trapping mid 140's and pulled the m3 pretty hard once they got going, probably traction limited or he is running boost by gear. There is noway in hell something in the mid 3k lbs range isnt going voer 145 with 1000 plus to the wheels.

        Wow thanks Sticky lol.It was a good race with Chris, I feel i will have to work hard for the next one!Black Bnr32- I would say i actually had a bit more power that day we raced, I made the 659 on a 80 deg day... The day we raced it was close to the low 60's.... I think what it comes down to is Power under the Curve... Chris' car really only makes 1000whp at the top of the RPM, It probably averages much less.. Once he does the things he said he is going to do, the car will be a different animal!!

        My buddy had a k20 rsxs with a full race engine all the goodie and a gt35 turbo, he ended up in the mid 600s to the wheels and went 10.8 @ 138 before getting kicked out. He also used the base 5 speed rsx tranny and went through like 4 of them cause mid gear the gears would just let go. I saw that 10.8 run and dear god that car was so much faster, 1.8 60, slow 1-2, slow 2-3 and then he let her rip with tire marks past the 1/8th lol

        Turbo Teg has a 6,8 s 60-130 mph Stage 5 m3 goes close to 6,8 s 60-130 car. I am impressed, this 6,8 s time is a cursed value. Taza Vick was also stuck with a 6,8 s time.Thanks God I broke the 6,8 s time barrier.Keep up the fast and good work.

        Mert- the 6.8 60-130 was last year with 125whp less than i have now... Big difference.. My 60-130 is probably in the mid to low 5's range....

        I would also say the HPF car is in the mid to low 5 sec 60-130

        As the HPF car sits now, once they revv it higher it will be much better

        What was the range of that race(xxmph-xxxmph)? I'd think that gearing, aerodynamics and power delivery played more of a part in that victory than the weight difference. Impressive any way you look at it

        Well, the thousand pound difference is important to note.

        Damn, you guys got up to that speed pretty damn fast! I've been thinking of building a ~350ish whp integra.
