Twincharged Civic Hatchback
I completed this build a while back but the owner finally came back in the states so we went to get some tuning done on it. heres some build pics and vids of the car.
ls block (bored/stroked, sleeved, 8.5:1 pistons, and h beam rods) gsr head (hog ported, lightened valvetrain, stock cams)
mp60 supercharger from a jackson racing kit
t3 60-1 with .82 hotside and anti surge shroud
38mm tial dumping and a 3 inch exhaust with single muffler
aem ems with 880's
garrett core intercooler in backdoor config with tial bov
the supercharger is bypassed once the turbo builds near full boost in hopes to keep the top end lively and still keep the low end grunt to get the turbo to spool. coming out of 30-40 mph corners there is hardly any lag and 50 mph corners there is no lag what so ever. dynoed on 93 octane

converted from an auto x car to a nasa tt car/scca hillclimb car. the owner is planning on running one lap with it also.

Re: Twincharged Civic Hatchback
So...what'd it dyno at nog?! I heard someone say 420 or something in the vid. I would assume this is Roger McDaniel's old SC setup, as the bypass looks exactly the same, and I know the new owner was overseas for a while. IIRC Roger's B16 made something like 370whp with a fairly big turbo and the SC.
I'm surprised you guys didn't go with a full-T4 setup, something like a divided .58ar, p- or q-trim. But then again its a roadrace car, and probably won't run wrinkle-walls. :1
If you can, please post the dyno graph...that would be ****.

Re: Twincharged Civic Hatchback
yep its his old setup, the bypass is completely different though....
yep thats the car. it make 441 whp and somewhere around 340 ft pounds on 93 at 25 psi. the owner of the dyno said that their numbers on that dyno read 35-45 lower than just about every other dyno. i can talk to the owner and see if i could get the dyno from it but like i said earlier its not reading completly accurate. i would love to get it on another dyno and get some 110 in it and accually try to make some power. this turbo can make alot more power if we want it too.
as for the turbo choice, its really quite hard trying to pick a good one for this setup since its so off the wall and no one has done it so we took the cheapest route and would run it a while so we can get a feel for what the car would like to use for later on.

Re: Twincharged Civic Hatchback
yea the return is deffinetly borderline. debated a return pump but thought we would give this a try first. its downhill and very short and has about 2 inches of straight for it to go down first. seems to be working well.
cut a hole in the intake manifold after the supercharger with with a throttle plate that opens with a boost activated acuator. air takes path of less resistance, preso.
