Burk here...Burk out performed the T1R at 500whp btw

 

Gah! Now I'm torn, thinking it may be worth the wait. LOL What kind of gains were seen from the Toda to Hytech?

 

Anyone have a before and after dyno of stock header and after market with a higher boost sc kit? Interested in some actual numbers as well.

 

The Hytech, some cam timing and fuel adjustments pushed the torque up 19 ft lbs at 8200 rpm.

Wow, that's amazing! Granted I'm not on a built engine, except for valve springs, TI retainers and the woodruff keys. But man, 19 lb/ft of torque with a header switch from a prominent header and a little tuning. I think that just made my mind up there to keep my order open. Hopefully they can fulfill the order soon though. If Urge is still willing to let me test their prototype header, I'd be interested to possibly see the differences between OEM, Hytech and the prototype.

I guess my biggest concern right now is fitment of the Hytech if I get an exhaust built. I understand that the Hytech is longer and you have to purchase the Hytech test pipe along with it. I guess my question is, will it bolt to a conventional catback location? I'd really hate to have to redo the exhaust if I go from stock and test pipe, to the Hytech and there is a length discrepancy.

 

I'm running the PLM header. Figured it's a copy of the J's header and not significantly worse than the OEM setup. It's much lighter which is a big bonus.

If anything, I'd be interested in the Urge design. But for the money, a couple HP gain doesn't interest me much. You can just as easily crank up the boost 1 psi and save your money.

 

Another great option would be talking to Burns Stainless and telling them your setup and having a triY made to your engine spec.

 

To the OP: Turning up the boost always trumps the very small gains you get out of an aftermarket exhaust system on a supercharged car, the benefits of an exhaust are not as drastic as they are with a turbo. The limiting factor is how much flow/boost you can produce from a blower, since they are all limited to about 20ish psi when fully dressed in aftermarket high temp bearings. Out of the box the Comptech Novi 1000 will produce 15psi on stock compression. So until your ready to max out what ever blower you have, any money spent on a header is really a waste, when you consider the stock compression motor will take 15psi easily with a good tune.

When you have a set up like sideways and decide to run that low of compression, it severely reduces the efficiency of the motor and takes every bit that blower can spin to produce power, the only place left to look is top end efficiency to make up the difference, with improving the breathing. So he took a different path with a supercharger with the super low comp, ported/higher flow head and therefore exhaust to match the flow character of that head. The results will not be the same on a stock head with the same exhaust system. There are several guys that have proven that you can make very much the same power as sideways on a stock uncracked motor with stock exhaust at similar boost pressure. Just for some contrast, one of our local members set up was a vortech blower spinning to produce 13psi on a stock f22 with a rev limit of 8400 rpm. He was running the factory header and cat back with a TP. He produced a strong number of 430whp/279trq on a Dynojet SAE corrected. That blower had room to spin yet. I don't doubt he could have netted 450+. So again, the point is the stock motor takes a lot, its very efficient with stock compression and stock diameter piping, and until your ready to max the boost your blower can provide, it makes little sense to spend good money on very small % of efficiency, and you will be lucky if you don't end up going backwards and losing power as a result of your decision to go aftermarket. Run a TP and what ever exhaust you have right now. Run the boost you want and see how the car feels and what it makes, if it isn't enough for you, up the boost to max the blower. If it still isn't enough, get a Novi 1200.

The Hytech test pipe is shortened so the exhaust attaches in the same cat back location.

Have you talked Burns into building you something? I never could. He is into Corvette ZO6s now.

 

yes i have. in fact all our headers built in our shop use burns material. speaking of corvettes, i have some material to build some new headers for my zr1 on the way
