KB 2.8L or TTiX
I'd like to get some input, I'm going to make a choice on what FI system to go with in the next week or so and I'm on the fence. I street race and drag race often.
Heres my choices:
KB 2.8L w/408
TTiX w/347
Whats some of your guys thoughts on either one of the kits. I know the TTix is proven over and over again, but the KB 2.8L with the 408 just sounds awesome. I'm not trying to get a debate started into what kit is better just what is the best choice for me or given the chance what combo would you go with and why? I've already got the ECS Fuel/Alky kit and a clutch etc...
Guys thanks I'm lookin forward to seeing some opinions.
Thanks,
SC

Like you said the ttix is proven at the track. The 408 kb isnt. Plus you may have problems keeping the trans and rear together with all the tq the kb well make. PM sent

Unfortunately, your gonna get VERY one sided votes. Whatever the person has is the one they are gonna reccomend.
I personally own the KB 2.8
If I was gonna drag race ALOT, I would probably check out the TTi-X.
If you predominantly run on the street with the occasional drag race event, I personally dont thin a TT holds a candle to the power output of the KB. (I mean power under the curve)

. I was actually inspired by your car and all that torque. Is your car hard to drive on the street? What is the car like on top end? The only thing that holding me back from the KB is there are very few results and no dragstrip results that I've found.
Thanks AMERICAN_HP

I don't even have turbos. I have the ECS Paxton and like it, but if I was making a choice between a belt driven supercharger and TTIx twin turbos it would be the TTiX all the way... Street or track definately the TTiX is best all around and proven so...

Based on what little information we have.....
I I was goin' for street giggles, I'd get a KB.
If I wanted to win races, I'd get a TTi.
I don't have either, but have seen multiple TTi's run at the track.

Well if you go back and read all the things AMERICAN HP had to go through to make 800rwhp with a 40Xci you would easily choose the TTi X setup. Now AMERICAN HP has done all the homework for you which is good. I have no doubt the KB could make some crazy power, but I think the TTi X is more flexible via power output. I also think you would save money on gas

Although KB do to twin screw design does have internal compression thus better adiabatic efficiency but it does slip at very low RPM. The parasitic loading at cruise conditions is negligible at a few HP. Just like turbine adds unwanted backpressure at cruise conditions, again negligible.
Where is Mark/MDHMI???

OK the only point I’ll differ or argue with is gas mileage the rest I’ll leave to others… The KB just like Maggie have a bypass valve that reduces parasitic drag while driving around, or it prevents boost from being made.

I'm surprised you haven't got flamed yet for saying the two words street racing. But both kits can make a killer fast car. But there are other varibles that can make each kit a winner or a loser. Traction is one of them. To get a hard launch from the turbo from a stand still, you need a trans brake, or N20 to boost the motor up, where you don't really need that on the KB. But without really good traction, and a driveline that can take the punishment, it's not going to do any good. A proper Turbo kit will have more room to grow. All you have to do is change to different turbos. With the KB, you are pretty much stuck with the same size of compressor. Also, the turbos don't have the heat sink issue that a top of the motor supercharger has. But the KB doesn't have any lag. External oiling. And has a free flowing exhaust system. There is pros and cons of each. I think it's just a personal choice that one has to make themselves. There is no "one is better than the other".
