Back up and running with new tune on TT notch

After blowing headgaskets at the track, I made a number of changes while the car was apart.
1) switched explorer intake for edelbrock performer
2) added 3G alternator
3) added mark VIII fan
4) FRRP AC eliminator to replace old march one I had
5) Replace broken plastic PMAS MAF with metal one (free replacement under warrenty)
6) Changed location of IAT and coolant gauge sensor to be proper

The combination of changes had the car running horrible. Limped it up to SGS (used to be Kauffmans) and had it redynoed and tuned. Not a very willing patient was my notch. Major ordeal to get the old O2 sensor bung plugs out to fit the wideband. The wires kept pulling the dist away from where it was supposed to be set before the final tightening. Anyway, 2 hours later on the dyno she is running sweet again. This time the tune is more conservative. Actually very conservative with 19 degrees of total timing. Making 416/502 to the wheels. Previous number with 23 degrees of timing were 426/520. Don't know if it matters but the old numbers were done in like 10 or 20 degree weather and this was mid 90s. But I am just happy to be able to drive around and enjoy the car.

nice numbers

and yes temp makes a HUGE difference in horsepower made.
you can easily pick-up 20-30rwhp by dropping inlet temp 70+ degrees

and I think its like 3-4 hp per degree of timing so you
have about 15hp in the backed off timing too.

Awesome Erich! I think that 19 degrees will make them gaskets last a whole lot longer than 23. hellI only run 22 degrees total with the water meth flowing.
Theres an idea for you, the DIY water/meth kit.
always wanting more......or maybe just have fun driving it!

Thanks!
Yeah I am hoping that 19 will keep it together. I want a chance to actually get greedy for more. I mean drive it, run it at the track, extract some decent times like somewhere in the 11s. That water methanol injection would be nice. I am sure that would help. That could be rationalized even as a "safety precaution". The heads are likely somewhat of a restriction too.

Nice numbers! Are you still running the stock fuels lines? Seems like you might be close to using it all up.

yeah stock rails and lines. Those should not be a problem at this level. It is a blast to drive for sure.
