It is higher octane it just needs more fuel for the same power level; it actually burns much cooler as well.

yup needs about 30 percent more fuel. it burns cooler and is higher octane than 93 (about 110). i get e85s for $2.39 anf 93s are going for $3.40 so even if i have to run 30 percent more fuel im only spending $3.10.

im glad you are happy with your car. what was your duty cycle and a/f ratio with 750 cc injectors. when i was running 1000cc injectors, i was at 95 percent duty cycle at 21 psi. dyno numbers can vary but injector duty cycle doesnt.

 

He says he is running 675's and is claiming 451 whp with 18 psi of boost at something like 85% duty on the injectors. His fuel pressure must be around something like 90 psi at full boost to do that. I don't expect that fuel pump to last too long and/or injectors.

 

Here is all of my mods and as far as numbers cant say for sure need a dyna pack dyno to find out just keep spinning on a dynojet or any other roller based dyno. as soon as i can get to a dyno pack i will give numbers and vids for all to see. BTW Fperra and i have a very similar setup but i am sure that he is most likely whooping my ass as far as numbers go.

here's my dyno chart.


my set up is:
gt3076r 63a/r
lovefab mini-me
3 inch downpipe and exhaust
inlinepro 3mm hg
rc750cc injectors
homemade intake manifold.

 

360 WHP/233TQ
Comptech SC with AC.
9# pulley.
AEM EMS 1052.
650 RC injectors.

 

hum...same year as my car, but running more boost..our numbers are about the same.I'm running a 8psi pulley.

 

spiff

w/ a 4 inch exhaust, you better be pushing upwards of 700whp to warrant that large of piping.

 

heaser primarys are ram horn style 2" with 3" downpipe and at at full boost with c16 its in excess of 800 hp. Everyday driving it stays around 1.5 bar with 550 to the tires with 93 pump and believe it or not i still have back pressure dont ask me how but i do. Havent had any problems with the way it runs or even afr's. My biggest issue is trying to keep it tuned as the seasons change in the mtns of of NC. All 4 seasons are distinct and have to have a retune per season. gets kinda of expensive for house calls but at least it stays running great.

 

But i can assure it has on heck of a unique sound with 4" pipe and a 4 in 4 out magnaflow muffler.

pm me your email and i will send vid
