Nice John.

Looks like the cams peak around 7600 rpm and carry it to 8k. Very nice.

Did you try leaning it out when you added timing since you are on a race gas blend? Also, there should be no reason you are at that MAF frequency at that power level. What size is your MAF housing? Either way the curve looks really nice and some good solid numbers to kick things off.

i never thought the engine would move so much air that it would do that but it dose but dose i think the maf housing is a 3in im going to look at that later i did not want to push it any farther until i get the maf maxing resolved these cams move the air

Nice.

What's she flowin lb/min wise?

mrbelvedere

iTrader: (3)

i did not think to ask i was kinda like wow on the maxing

Fix your **** John there is no time for non-***** out numbers! jk good baseline runs like I said. Gotta be fun to be back at it again.

Too many variables on an LSJ. I had stock blower "flowing" 49 lb/min with a raped maf on the 80's, but on the scaled 98's it would flow as low as 28 lb/min.

True. Just curious though.

it is nice to be back at it and I am more then pleased with things ill make the switch to e in the spring and fix the maf also

Would E give you better numbers than race gas? Anyway great numbers, glad to see it running.

He isn't anywhere near reaching the limits of the race gas, not even the 50/50 blend. The car is not flatout. Still pretty conservative!

ThexGovenor

iTrader: (2)

I figured as much, he was just talking about E. Just curious if it was for better numbers or because the race gas is so damn expensive

How early in the rpm range is the maf pegging?
I'm in the same boat, I keep my eyes glued on the afr if I take it all the way to 8 lol, ride out the last cell
I'm looking into a mini afc to fix this

Lovin the base numbers. Nice work John. Think you can bust 400 without nos by time you're all done?

Area47

John. The maf is not pegged, only the scaling. the maf doesn't max out until 16k hz. it holds the last cell.

Time for a 3.5" intake.

Wasn't trying to take from his accomplishments. He and I had a conversation about it as well discussing the potential the car has with what he has already made given the circumstances.

I discussed that with him as well. Don't be afraid to go into "no man's land" lol he is aware though.

advise

iTrader: (3)

Can you make you intake with a 3.5 maf housing
I'm tired of my car going rich when I hit the last cell

armcclure

iTrader: (2)

Stop raping the last cell then. Use PE.

Same difference as far as the PCM is concerned.

mrbelvedere

iTrader: (3)

I think so but not on race fuel

im going to try a find a 3.5 maf tube first

that's what I mean but pegged is pegged
I will carry the last cell as you said but I would like to get some room

yup
