Topgunz - air to air upgrade

EliteXpress · 07-22-2016, 08:06 PM

That sure looks pretty!

SlyZGuy · 07-22-2016, 09:52 PM

Can't wait to get mine!

TopGunz- the 500whp you mentioned by a member, was that on a stock motor? Did it have 9lb pulley and/or impeller upgrade? Contemplating if it's worth to upgrade the pulley/injectors or to just simply add the a2a. (Cost vs gains) I'm making 449whp now w/9lb pulley.

His name on here is Allenwang. You can try to contact him. No built motor but I think he has an upgraded impeller. Either way, there are so many scary stories popping up of what kind of harm the 9psi pulley is doing to motors with the water kit that I would never run that thing.

A local guy here in the twin cities just had major problems with it and is installing my kit once it's cleaned up.

Ever wondered why a huge R & D company like stillen voids the 36k warranty on the motor AND the kit if you opt for the 9psi pulley?

Yeah I gotcha man, I haven't been driving mine since putting the pulley on and learning all the issues. I'm awaiting ordering your kit when it's available so I can confidently start driving my car again!

Well the last two kits of the 2nd batch have sold. SlyZguy just picked up the last one.

Who else is interested in one? Should I get a 3rd batch going soon?

future370zzz · 07-26-2016, 06:08 PM

Does this upgrade kit require changing to Ecuteck tuning software and adding MAP sensors?

I'm trying to get a sense of total overall costs with my setup. Already have 1000cc injectors and 340lph fuel pump.

On the fence about going E85 and adding RFS.

What's the gas mileage per full tank are you guys with E85 getting on average?

milkcow500 · 07-26-2016, 06:20 PM

No, this fixes the MAF sensor issue, so you can run Uprev if you'd like to. I'm running a hybrid EcuTek tune that utilizes both sensors.

Ah, OK. I guess that's what the MAF mount relocations are for. I wonder what this kit will do with CA 91 craptane.

milkcow500 · 07-26-2016, 06:37 PM

If you have easy access to E85, then that would be your best bet honestly. I'm assuming you'll just have to gas up more frequently, but the overall price shouldn't be too different.

Well the good news is that if you stay with 91oct then you wont need a rfs. The only reason a rfs is needed is when you need to pump 30% more fuel due to E85's consumption.

Regarding the MAF's and tuning with Uprev... The stock MAF's should work fine with the 8 or 9psi pulley. However, if you upgrade your supercharger to the Si trim and start pushing a lot more air over that then they can be maxed out before redline. MAF's are strange. I had a long conversation with Sebs from Z1 motorsports about this (you know, the guy tuning most of these cars) and he said that they are a bit unpredictable. One car can max out voltage 1000rpm's earlier or later than the next on just about every kit he has seen on the market.

Again. I dont see this becoming an issue until you are maxing out the kit. And then heck, might as well get EcuTek if your trying to squeeze every last pony out of the car. We have seen it can pull out a good bit more over Uprev tuning. The MAP sensor is pretty cheap anyway.

I'm definitely interested in a kit Tops but won't he ready to pull the trigger til sometime in the next month.

anyone have any tips on getting the ypipe to fit better/easier? I've cut a decent sized hole in the radiator support so I know thats not an issue. I struggled for about 30-40 minutes trying to get it to fit
