Time for more power
Peak horse power went up 10over previous dyno . Lots of changes but one of them being a tq converter, hard to say how it effects it.
First pull through exhaust on 93 pump gas it made 540hp
Plugged fuse in to meth kit and it lost 6.made 534. Rich air fuel
Leaned back out to 12.5 & matched the 540 it made without meth but safer.cooler intake charge.
Opened exhaust to 18"x3" extensions and power went up to 553.
Added 1.5 deg timing but it lost 5hp.
Called it good for 93&meth
Pumped as much fuel as I could out and put 7gallons of e85 in.
E% came in at 50%
Set stoich to 11.6 &made a partial hit to 6000rpm to see it we were close on air fuel
Graph over layed the 553pull exactly but it was actually 10.2 air fuel and commanding 10.8. Was going to turn meth off to lean it out and see what it done on e50 alone. Got out the car and seen water on floor. Not sure if it's a head gasket but pretty sure it's just a coolant line on back of head loose. Will pressure test tomorrow and confirm.
This Basanni exhaust has been great but one thing I see compared to first dyno session was now the exhaust is a bigger restriction than last time. At the hit ,there is a 30hp difference between open headers and bassani dual exhaust. It lessens as the rpm goes up to a peak of 13lost at 7500 rpm.
Last time it was only 19@hit and 5 up top.
I think the motor is making more power but the converter shows less to tire.
It should scoot at the track, feels really strong on street. Converter is now an 8"fti non lock up .flashes 5100 & trans brake goes 5450.
I think if I could have leaned it out on the e50and added a degree of timing, it probably would do 560. Not sweating it though.the track will tell
qouted from my dyno thread
today I'll be tracking down a water leak. Hopefully it will be at the track sometime this month but possibly early November before I go

Ended my dyno session early thinking possible head gasket.
The water run down the front of block , on to the oil pan rail and to back of block.
Amazon is refunding me most of my money so I put a mechanical pump back on. I dont think it done much for horsepower and it wasn't helping with cooling so I'm not mad about getting money back for something that didnt work for me.

The Best V8 Stories One Small Block at Time
Edelbrock makes a higher volume water pump that doesn't work on our cars without some modding. But the price for it and the billet pulley is almost as much as the Meziere.
Normal street driving water temps sit at 228, when i get into it temps will go to 220. Only problem i have is when hwy driving, temps will go down to 195 so every 15mins or so ill drop it into 5th and give it a squirt to bring temps up to 215 or so
Modified that and seems to have fixed that issue.

I'm not concerned with temps now , I'm spraying meth injection 5o cool off combustion chamber.
I lined up with a friend of mine who has a vortech supercharger in heads cam and intake ls1 fbody who made 550running out of fuel pump with a 255walboro at only 5500rpms.. Since swapped it for a 450lph.
We went from a 55mph roll to 135& was side by side the whole way. Here's the kicker, he was alone on 1/4 tank of gas, I had a full tank and a 170lb passenger and through exhaust. He has the speed engineering dual exhaust, I have the bassani dual 2.5" and need to swap to the speed engineering dual exhaust as im losing 30hp to the wheels with this small pipe set up.
Because of him edging me out by a fender, his exhaust was right next to my window so data log shows I shifted second to 3rd at 7300 instead of running it out to 7800where it needs to be.
Great run with a good friend and we both laughed and just enjoyed the run. In no way am I making excuses for why he edged me out, i'm tickled to be running with a blown fbody even if he is only on 8psi boost.
Data logs show I was lean also. Yet I made another hit right after where it was perfect at 12.4 air fuel.
Seems the meth kit is saturating my air filter or something as it makes kpa go down to 92-94 and get lean then it will read 99 the next pull and be great.
Possibly gonna do a Chris 1313 pro stock ram air and 3" speed engineering dual as next mods
