Ya, the other station close to me(10 miles away) that sells race gas has 100 octane for $5 a gallon. The one I go to is 8 miles from home so I'm real lucky. I don't know why it is so cheap. They have special pumps for all kinds of special fuels. Funny, every time I go there they have a person announce on the loud speaker that those pumps are for racing gas only. I have fun with them. I say "Don't you think I have a race car". Those women don't have a clue what my car is but they say "Ya, it looks kinda fast". My brother runs it in his souped up FD to play it safe and also in his Dodge Hemi.

If you are talking to me I have 550 primary and 1600 secondary. The most INJ Duty cycle has been 81% on the Commander at high rpm and 20psi boost. I have a RP fuel pump.

Marshall, I got 404s on your links, so I guess it's my turn to try...

This is a spreadsheet I've been playing with for a little while. It's currently analyzing Ihor's run, but there are others at the bottom you can cut and paste into the power cells. Only modify the blue entries.

I look forward to any feedback.

I know that the conditions were different, ect ect, but I wanted to get an idea as to how much quicker the 3540 would make power than the T-78 on the average street ported motor. The 3540 may indeed spool quicker, but it doesn't look like makes any more power than the T-78 in the 3000-5000 rpm range -maybe because of flow? These were on the same dyno and around the same boost, BTW.
[/B]

the reason the gt3540 doesn't make more power down low is because of the aggressive porting. power range is shifted upward due to the advance of the mechanical timing. on equal terms the gt3540 will spool a lot quicker than the t78 due to the smaller turbine housing and the dual bb. the gt3540 is prolly better suited for a car w/ mild porting as it builds boost quickly and you can take advantage of that w/ a motor w/ more midrange power. at straight gt40 would probably be better for a heavily ported motor, spools less quickly but would have lots more top end.

Kyle, do you have an ignition upgrade? Mine seamed to be holding out on the dyno, but shortly after getting on the street I seam to have fouled out my plugs. Was getting ignition breakup even at 13 psi on the way home. I'm going to pull the plugs tomorrow and take a look. I did get one good shot at 20 psi though, and broke the tires loose in 2nd at 50 mph and then again in 3rd at 70+

I was in the car for all of this guys. I'll type more later (goin' out to get trashed for new yrs with Kan and alan) but it's pretty crazy to have someone break the tires loose at 70 mph

Also, your cutout was most pronounced above 1.30 on the power fc com boost reading, Ihor. Below that it wasn't too bad. Time to clean those race plugs.

Can't wait til you come out to texas to help us with Gotham bud

Cleaned my plugs and ignition cutout is fixed. I bought some race gas the other day but haven't been able to drive the car cause of the rain.

FYI Ihor got banned again so I dont know if Jason will let him back on (for those of you wondering what happend to him)
