Scheduled a dyno session!

[WhiteDevil]

I am pretty excited. I have two hours on the dynojet scheduled for july 31st. The numbers in my sig were just two pulls with 32 degrees timing and a little too lean A/F ratio when the engine had only 900miles on it. Its got 7,000 on it now and I now also have 1 3/4 long tubes. WIth this combo i would be happy with 335rwhp. I hope with some playing with the A/F ratio and timing i can get there. I may also do some comparison pulls between the C&L tube and my Anderson power pipe. SO that should be fun too. I am so excited!

Very nice numbers.

The comparison runs would be interesting.

I second the compairison of the C&L and the Aderson Power Pipe. Would like to hear the results. Good luck

Have fun John

It will be interesting to see what that combo likes.

I'd think 32 is not enough ... but ... you will see

I'd go there and baseline at 34 and 12.75

I've seen some Aluminum head combos go as high as 38

Wait ... I seem to recall you be a Calif dude ...

Ya'll aint got 93 grade gas ... do ya

If you only got 91 ... maybe start at 32

How high have you gone in your tuning John

I havent really played with it at all actually. I put it at 32 when i made my 347 bin and then i never touched it. I think i have all the timing in at 2,500rpm.

I'm curious John

Where are you now with spark and fuel

Well on the dyno run that made 327rwhp and 356rwtq i was at 32 degrees timing and the A/f was average around 13.4:1 slightly moving around. After the run i richened it up to 12.75 and now with my wideband i can monitor it. So as of right now with my PLX i see between 12.6-13 and am running 32degrees total timing.

Sounds like you are setup for a good place to start

If you can ... have each pull gathering data for later research
and
You can compare your wb readings against the shops wb readings
