Nice run. What was the boost and timing?

We have pretty much the same build but I am not running your mph.
What was your boost and timing?
Did you lock the tc?
Was this on race gas or pump gas+alky?
Thanks for any help you can give me to get that mph.

Nice combo then!

You really have to know what you're engine likes in regard to timing/fueling. I bracket/grudge race my car most weekends spring to fall...so I have a pretty good idea what I can/can't get away with. I'm up here in Canada...and you can make some silly HP in the fall when the air is "clean".

E 85 isn't available up here in The Great White North.

I know I can push my boost/timing further currently 25#/20*) but I am just curious as to what boost/timing you are running. Are they really high? Are you running race gas or 93+alky?
The weather here will be in the 40's this weekend when I go to test and tune, so that will be fairly cool.

I think it would hurt your et and mph if you were to lock your converter. It will drag the rpm down too far through the 8th. After the 660' it might help though.

Wish I had kept my 6262 and just swapped to a bigger turbine housing. Those times are pretty good Scooby. I think there are some 1.4's to be had launching it in the sweet spot. My best mph with the 6262 was 103mph but could only manage 7.0 because of traction issue. Every single pass I made I let out the throttle because of wheel spin/hop was so violent.

There's a little more left in it. The 60's were pretty much maxed out...so I couldn't go all in. Going with 80's and a 340 LPH pump next spring...and the fuel line kit from Racetronix. I'll max the turbo out and see what it does. Goal is 6.5x at 106.x.

You'll kill that goal once your fuel is straightened out. You are close to being ready for a 67mm.

I agree with 20psiofevil. Locking your convertor would likely worsen your 1/8th mile time. I use an old skool AC 16930 NL convertor...seems to work well with this combo. The governor in my trans is altered somewhat...so it shifts a tad higher than stock.

Very simple stupid , great job . Those 6262's are nasty , great turbo

 

[leirch]

Very nice times. Can you tell us how much boost you were running? and total timing?

 

[SCOOBY DOO]

High gear timing was on Erics default setting...low gear timing was 4 degrees over his low gear default setting. I ran 112 octane that day. Boost was in the mid 20's.

There are head porters...and there are head porters... and the guy that does mine is the latter. He also backfilled and contoured/matched the doghouse for the Champion stock appearing intake. I also run a Champion 3/4" spacer with a Steve Monroe 62mm TB.
