For those of you with the C38 kit, could you please post your Fuel pump size and Fuel injector size in CCs?


Also, what horsepower you're making. I'm trying to decide on a combo for e85 with a goal of 380 RWHP.

I'm going with the c38 but I'm staying with stock injectors. Need to keep the car as a daily driver. 300hp should be plenty.... Until I get hungry for more Lol

Note:

I was thinking 725 CC grams injectors to play it safe, but not sure if I need o upgrade the Rear FP.

I believe @Airboy did my tuning, I don't think it was a canned tune.

The quick options, through us, are the Grams Performance, 550cc Injectors and 265lph Fuel Pump.

There are a few C38 customers now, with E85, making close to and beyond 400whp on the right dyno. High-Boost and E85 should have the vehicle around 350-375whp in terms of a more common, average HP figure.

Thanks! I have been looking at exactly those for some time now, only need to save a little bit more and I can pull the trigger!

Well just let us know! I'm sure @fteightysix could oblige with good 'package' price as well.

I was running Grams 750cc injectors, running a Moto-East tune and KW tune, and the car was running great, Went to Flex fuel with the Moto-east kit, and Bill at Delicious Tuning did that map. The 750's would be fine with the Moto-East tune or KW but i guess Bill uses a little bit more port injector instead of Direct injector so we bumped them up to 900cc's as i was going a little on the lean side above 7k and im running a grams 265lph now, i went through a few different pumps as we were trying to find a tuning issue, and Church thought it may come from the pump. The walbro are not e85 compatible, where as the Grams is, so thats back in the tank. Me and Bill are still working on the tune, its on the rich side up top and can have more timing according to what was shown on the dyno. I just have to make a appointment with bill. Church thinks he should easily get 25-35 hp with some more timing and leaning it out and still be on the safe side. which i want to be at. id give up 50 hp and be safe then have that and be on the edge. Im on a little bit higher boost setup also. My AEM failsafe shows 19psi though on churchs dyno his set up only showed 16 with a slight jump at the end to about 17psi.

I put 417 to the hub..

That's interesting, considering those are completely normal numbers when adjusted to a dynojet - I made essentially the exact same numbers with a standard KW belt, lower boost and only 550cc. With 4 more pounds of boost from the high boost pulley and 350 extra cc that's disappointing.

On a stock exhaust and header with the same FlexFuel kit from Moto East and tined by Bill at DT.

This kit looks dope!

[SPCorBUST]

Didn't mean to bash Thomas, just thinking either there may be issues with the car other than the parts, maybe the upgrades aren't worth it if there aren't any gains, ore some other issue. Just seems like you should make more than standard numbers with those upgrades.
