    • 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.

        With as much power as both of these cars are making, 160mph comes up FAST.

        No doubt. I think some aero changes are in order.

        The Acura is 1/2 a ton lighter... not a ton lighter. The M3 doesn't weigh 4500 pounds.

        Very impressive! Do you have any work done to the gearbox? Different gears or diff final drive?

        Stock gears still... That is one of the limiting factors lol... They are not that reliable over 350tq, i have broken/sheered off gears before.. This trans has been taking like a champ tho! Stock Open diff too...

        Great video... Very informative. Definitely a power to weight ratio issue. Can't wait for the next run.

        How the $#@! did the intergra get traction in an open diff. And the gearing is not that great in the integra if i do recall. Hats off to gringo your a G...... and the m3 has better lbs per hp ratio.....

        Ive always had an open diff, and being as the car is corner balanced up front both tires have the same weight over them.. so it helps a lot with traction..

        You'd be surprised, the gearing is awesome in a GSR.. Funny thing is i calculated the gearing of Chris' car and mine with our tire combo and our shift mph's in 3rd, 4th and 5th are within 1 mph of eacher!

        Not once you add the downforce that M3 is producing.

        But hey, run what you brung. Hats off to the Teggy. I always give Intergras props when e36 m3 guys say they are slow. I just say "yea until you look beside you and wonder why he is still there" Click here to enlarge. Nice to see you guys actually get it onClick here to enlarge instead of paper humping like some like to do.
