Now, once you add the supercharger to the mix, the supercharger is literally shoving more air into the engine, and it has to go somewhere. This extra flow, is what truly allows the Ace to shine. Even with stock cam timing profiles, if you tune on an Ace header + C38/C30 HBP + pump gas, if you swap on another header with just that ignition timing table, you'll knock before you can redline; the Ace just flows that much more and allows for more cam timing. Here's an example. JRSC C30 + Ace header + flex (E70)+ HBP |

People blow built motors too at less power. Shit happens. I think JR is trying to suggest that the setup is clean for the stock block for practical applications for most people.

I have been at 12.5-13psi (85mm pulley) on a Harrop SC and E85 for over 6 months with a conservative tune as well. I haven't blown anything. The Edelbrock kit comes with a pulley that is smaller than mine, and the Edelbrock kit comes with a warranty, so I am not surprised JR assured him all would be ok. Adding E85 makes more power, but decreases the risk of knock and keeps temps down, so it is more of a trade off, and it gives room for a conservative tune.

So far my only regret is using 1,200 cc injectors, too much fuel when driving slow in the city. Other than that it drives great, seeing AFRs under 11.2 at full boost which is only reaching 10.7 PSI. Going to Daytona next week, we'll see what happens then.

All of my worries about not feeling enough power down low were put behind me after I finally installed the kit alongside my existing A350. It pulls hard from 3k and up, even at partial throttle! |

Injector size doesn't affect MPG on this car, as we have both DI and PI, and the DI is used under light throttle condition unless you have an unusual tune. |

The other thing I was advised of but haven't experienced yet is that if I have to use pump gas (93) instead of E, the car will have a hard time starting because again, too much fuel and the timing on the injector can't be reduced further. If all this sounds like a bunch of crap, please let me know and I'll find a different tuner. I can take a log and look at the real numbers, the 11.2 was me just glancing at my gauge quickly while driving. I have a track day scheduled next week, if you don't think the car is safe to drive hard based on what I've said let me know. I can get a log once it stops raining. |

However, street driven GTRs and such, all drive just fine on injectors larger than 1000. 2000cc injectors on street driven cars is not rare nowadays, with how much development there's been. If you're on ID's, then the injectors are already pre-measured to make the tuner's life super easy. Give your tuner the opportunity to make it right first. If they can't or won't, then Zach (CSG) can tune your car. |
