8.54 at 161 on a 1.35 60ft

Twin Turbo Mod motor at BG this weekend. Weighs 3425. Look at the IAT

 

[pacecarta]

76.0 is that celcius

thats about where mine usually goes when the alky comes in but it stays there the whole run ,
how cold was it at the initial onset before it climbed to a sweltering 76degrees

heres a snap of a 130mph run.. 93 and meth
inlet held steady at 83.8 when track inlet temps before launch and after on coast down were 140

What size injector?

Dito. What bison said .

That 1-2 shift was

Figure outside air temps at BG this past weekend where in the 60's? The thing is when you start making power that IC becomes an issue. Whether its not big enough to support the air volume or becomes a restriction.

High temperatures this past weekend @ BG: Saturday 63*, Sunday 67*.

So he was 10 DF over ambient at 25 PSI boost

th400 rvmb shifts just fine and drops over 800 when i do get the revs up to 6k but on that pass the 1-2 looks bad but was all wheel spin , the 2-3 looks weak because i was still spinning up to the shift and just pulled it to third a little early just a little above the stall and it spun then too ..

heres another taking it easy 129.9 pass shifted 6320 1-2 and 5850 2-3
, ambient was 88 surface inlet temps were 120 temps but with alky inlet was 81 across the board

Nice, what sized nozzles were used?

Also, is this an E85 car, AF/R looks like it with Meth Injection?

 

[Dusty Bradford]

He needs a converter. lol

He needs a converter. lol

How can you tell? How much should RPM drop in between shifts?

 

[pacecarta]

he could also be commenting on the 7350 engine speed vs the 6200 drive shaft speed , thats a bit o slippin

15%

You got it. 15-16% in an 1/8 isn't bad. But in a 1/4 that's a lot.

Something I found interesting was that half his engine is at 9.3 A/F and the other is at 10.2 A/F. I would hope he doesn't have the second O2 calibrated correctly.

Hey guys this is my car. Julio has been great with support on the meth kit, it has worked flawless for three years. I am running a 10 & 15 nozzle. The fastest I have been so far is 8.88 @ 154 on 93/meth 21psi. I just put a 10pt cage in it over the summer to get ready for BG so I turned it up to 25psi. I have not ran the car at this boost level yet so I was on race fuel(114)/meth all weekend. The a/f is low 9's but it runs well and plugs look fine after a hit.

I have an external wideband I am logging with the fast on the other bank also. It's an innovate lc1. I am not so sure how accurate it is when a/f goes below 10. If I make pulls off meth the two banks will be within .3 of each other. On meth the fast always reads a point richer.
