Alright guys, here's the official word on head shimming from our Andrew, our engineer: With the Mav, any 91 octane pump fuel turbo setup (always use high quality 91!) will require compression to be lowered, either via a head shim and/or low compression pistons. Stock engines are fine on E85 for low boost, and if you're running race fuel you can run higher boost on a stock engine- we're estimating 8 psi on VP's 110 race gas, and up to 14 psi on VP's 115. We are currently discussing options for what will be included with a low-compression Aerocharger turbo kit; our priority has always been to deliver the most complete package for a comprehensive install.


On another note, here's a pic of our air/air intercooler production sample that just came in - this option's going to come with a custom ram-air hood scoop. We'd like some feedback on what we should do for finish options, should we polish it off or leave it looking rough and industrial?

Polishing is going to probably add cost to something you are not going to see very much of. I'd rather see more put into a nice replacement hood or reduce the price of the overall kit.

I say offer both options. Polished would obviously cost a bit more due to the work required ands the bling factor......

How do you plan on getting around this issue with the Wipple charger?

I'm tired of waiting for these guys to pull their heads out of their asses. I'm gonna put in a garret gt-15.

Here's the dilemma, they've got 3 different versions of Thai turbo and the difference is trim, AR, among other things. So in having a tough time deciding which one to go with. I do t wanna copy the popos but I've no other choice. I'll use the same one that they're using in the 1k and I should be pretty close. I don't think I'll need an intercooler because of the length of the charge pipe to the throttle body.

That's about how much I know up till this point. Any input or tribal knowledge in the area of sxs turbos would be appreciated.

gt15 was fun it the woods zero turbo lag but fell off quick i would think you would need something around a gt20 or bigger

Like I said there's 3 different versions of it so I'm guessing they ran the biggest one? I'd like to go with the 20 series and one of the ball bearing chargers for efficiency

No it's all good! That's why I'm bouncing ideas off of the guys who've done it or are at least educated enough to have an intellectual conversation. I just dont wanna go too big and get turbo lag. I want it to hit but not right at 8000

Maybe look at other vtwin powered bikes that have been turboed, Harley's?
If your running stock compression a water to air intercooler would be a must to stop detonation. The barrel type water to airs are good as don't take up much room then run 2 water lines up to the evaporator in the back.Remember the knock sensors will retard timing if they sense any detonation, unless your going full ECU.

My new aero charger intercooler should fit great

That's where my radiator is bring relocated to. If I remember right, silber had an option of an intercooler. It said the hp gain was minimal because you were able to cool the air long enough after the turbines in the charge tube. The charge tube is close to 7'-8' long. Which in turbo world is like a mile

My gt 1544 started boosting around 3000 and the turbo I'm using now te04h Is around 5000. Since the new ecu reflash is available it should make the DIY turbo kit A lot easier to tune and run without the damn limp home bs Problems
