2300 install
I have a 16Zm7. Prior to the 2300, I had kooks LT, AFE, 15% pulley X tank and tuned. Made 621/690 on 91 octane. Prior to the install a BMW tech came over and cleaned the intake valves and ports. They looked brand new. Install included a 5% pulley. Wanted to keep my ATI balancer. I was told that I might run out of fuel running 91 octane, and I did. My high side pump never wavered but the low side couldn’t keep up. It started fine at 71 psi but dropped to 41 at the end of the runs. Compounding the problem was the temp in Santa Clarita ca was 100 and some what warmer in the dyno room. AFR was steady at 11.77, boost just under 14 psi. We made 661rwhp we kept spinning the tires on the dyno. So we really don’t know the exact tq number, best we showed by walking down on the throttle and not stepping hard like you normally do was 690. My tunner has already secured a 2019 ZR1 low side pump which should take care of the problem. I’m sure had it been in the 60 degree range the numbers would have been better. This is a street car so no meth or E 85. Car runs awesome in the morning. Very happy with the car. PS, I was going to use the MSD pump booster but learned it does shorten the life of the pump. So the ZR1 pump was a no brainer. So build is not quite done yet

I am not far behind u. Waiting for the 2300 to arrive. How does it feel driving vs the 15% pulley and oem unit? Was the manifold temp better controlled? The 5% pulley was good for 2psi I guess, good to know. What part number for the ZR1 lowside pump and is that direct bolt-on? Same plug? Enjoy and safe driving... 👍

its got more than before the 2300. I don’t have the part number my tunner does and I would think it’s drop in. Once it’s retuned with the new pump, tunner said we could go back to the 15% . Not sure it’s needed. In any event power will be up with the pump. It feels strong. It was so hot that day I couldn’t really say that the IAT’s were much different I’m sure the were

Tell your shop to have the rollers addressed. You're not spinning for power reasons. You're spinning because the rollers are worn. Owners dont like to do this because it cost several thousands.

So you picked up 40rwhp by swapping out the S/c but also going down to 5% from 15%. Everything else stayed the same? (obviously adjusting the tune was required). When does it go back on the DYNO?

Yeah I always kind of shrug when I see this. I put down 850/800 rear hp/tq on a dyno tune and never spun the tires. Always used two tie downs in the front and two criss-crossed in the rear, may different cars at many different multiple boost settings 550-850. Wasn't in Santa Clarita but was 45 miles down the road in Oxnard.

as soon as I can get the low side pump in. And definitely not tune on a 100 degree day.
next time I’ll wait for a cooler day to tune

Interested on the 2019 fuel pump if someone does get it to work several members here have tried and bought them but I haven't seen where they work.

With my car we have over 200 more in horsepower
The complete petrol system has always remained original.
The engine electronics must be perfectly adjusted and you have no problems

Face it. We got stuck with a small blower running too hard. Was it because if European pedestrian safety standards? Idk. But I know that whoever decided spinning a smaller blower faster for a track car should be reassigned to the I dont get it division...
I recently watched a bob lutz interview from a few weeks ago on autoline after hours and his comments regarding the C7 were interesting.
gm did a great marketing trick with the C7 and the guys on whatever teams did what they could but they were out of chassis at end of c6. Tadge TOLD Lutz. But 2008 happened. Corvette didnt die thankfully but it got a haircut.. and I guess the blower/engine team tried to put a budget blower on the car for numerous reasons (although they claimed it makes boost quicker to match the hi quick revving LS7..sure it was).
just wish they kept the 2300. Saves us the 5 to 9k of installing it ourselves to fix this thing. It runs cooler and is better in every way same footprint. Unreal.

is what I’m going to install. It’s what LPE recommends. It works only under boost conditions. And that’s what I want
