• 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.

        Should make over 700whp would be my guess... So another 50+ whp and cams should allow for a better powerband Click here to enlarge



        The fuel system will be a Dual Walbro 255 inline set up in parallel, i have to sump my tank also but thats not hard...

        Yep, excess drag.
