Hi everyone,

Car: 2015 M7 C7Z Z07

Mods:

F1A PC and tune (~17 PSI)
Alky Meth
AR 1 7/8" headers
Stock exhaust
Lots of cooling mods (CR primary rad, GM secondary, Dewitt oil cooler, CR catch can, billet 160 thermostat)
GT35 Lingenfelter cam 38% fuel lobe, and their High side pump
CPR Low side pump and larger line
Springs and retainers with DoD delete.

~870WHP/776WTQ

Track to test and verify...A huge thank-you to Manny Dasilva and his DMS Team - especially his Tuner - Dave Rempel who put alot of time, sweat and tears into this build to get it right.

Awesome man, great numbers! Thanks for sharing.

Can you compare any data from the high side fuel pump?


Like can you see a big gain versus stock...etc

Thanks Jbs - I was happy with it. It seems 900 WHP is the limit for the F1A (I'm not sure about F1A-94).

I wanted a street car so I am happy to leave it here. If I wanted a record setting car - I would have went A8 first and at least an F1R.

I have a set of 18" wheels and DR's going on to hook with...

i appreciate it - thanks!

We do have more boost available to us but fuel is still an issue even with the high-side and low side additions - adding to the cam. It seems to be more about the injector spray window versus the size of the injectors.

Lingefelter stated that the whole package - including the 500 dollar a pop injectors would add about 20 percent more fuel (cam, high side and injectors). I did not get the injectors - but we saw about a 20% improvement overall. Many builds are going triple meth lines and even port injection (halltech) to remove this issue.

I would have to ask my Tuner the differences he saw just with the high side - but what I can tell you is many built C7Z cars have had issues with the stock high side. The secondary lowside and line was very helpful as well.

Very Nice numbers congrats. can't Waite to put my f1a-94 on in a few weeks

I appreciate the info... I have the 38% cam with low side and dual meth with a F1X and out of fuel at 6k at 1000rwhp..


Just wanted to know if the high side did add the 20%ish before ordering... Or go the port route but cant get a shop to respond to their setups to decide....But im impatiently waitng


Keep us informed on your car


Side note does your front plate effect your Procharger cooling?

I hear your challenge and I can tell you some people are adding a third meth line instead of going port injection - but overall - it just seems until the tools can open up the spraying timing and allow a longer injection window, for bigger power it seems you do what you have to do to get the fuel. The high side helps as again many of the stock units fail - some pair them up.

I really love my C7Z and with this setup I think I will finally be happy performance wise, but I have a twin turbo setup on another car - non-DI and man is that an easier platform to make power on lol. Because of the other car I am more than happy with this performance for a street car.

I haven't had any issues with cooling with the PC setup plus all of my cooling mods. I would say the license plate is not helping air flow though - so it would likely be better off without it.

Good luck with your setup!
