I'm suprised you didn't hurt it worst than you did with that hot of a spark plug your lucky iit only burnt the ground straps off I would go to a non protruded gap and a #9 or#10 as already suggested. The last blower motor I work on dyno testing was a 484 C.I. 426 Street Hemi, it liked 33 degrees with 7 lbs of boost using a 10:71 Littlefield roots, no intercooler, running 12 % under on CA pump gas, that combination made 927 HP at 7300 RPM after doing a lot of small changes on it to sneak up on what it wanted. We got greedy (the owner wanted more) and switched the pulleys around to make it have 13% overdrive, switch it to race gas, back the timing down to 25 degrees total and made another pull, it started into detonation slightly at 6500 RPM and still made 1027 HP at 6500 RPM (we pulled it to 7500 RPM on all the pulls except the last one) I moved the timing up to 28 degrees total and ended up aborting the run wjhen it started to go into detonation again Luckily it didn't hurt it I switch the pulleys back and told him when you get it to hook up with the pump gas combination call me and we would hop it up again,I never got that call My meassage is back that baby down some to be safe and then sneak up on it Maybe some day, if I ever when the lottery or my ship comes in, I'll try a compressor on some of my own junk, twin hair dryers with intercooling and EFI

By switching from a msd digital 6 to a digital 7 (7531) got rid of top end miss fire and the ability to run the largest nozzle snow makes. Was able to add more timing and went from a best of 10.02 to 9.46.

I've read alot of bad things about running meth if you don't have almost perfect distribution across all the intake runners...don't know this from experience though. As for the wideband, I've got a LM-2 Innovate and I love it. It kept me from pulling my hair out trying to get a good safe tune. I run 93 pump (E10) on the street and 100LL avgas when I want to set it on kill. I've been as high as 18lbs with cast pistons and avgas, would have never felt safe doing it without a wideband




So what's going to happen when 1 cylinder gets more water then the next? I know of a person that injects it before the turbo and after the turbo and in the intake and was able to make 1300+ hp with a small block. We are not talking fuel here this just lowers your combustion temps. The more I inject the more hp I see on a dyno time and time again.

Thanks for the info on the LM-2. I'll look in to it. Been running straight distilled water in my Snow system. Might switch to winter windshield fluid just for the next month or two.

As always, thanks for the info Cab. Definitely making a plug change and going back to the 4" blower pulley ( from the 3.7" ) until I can get a handle on it.

Looks like you got lucky.
I've lost the straps a couple of times over the years. It never did any more than put some little pits into the top of the piston or head... and sometimes they rattle around and into an adjacent cylinder to rattle around before spitting out the exhaust too! LOL

When I tore mine down after quite a few miles and "incidents" like that (unintended overboost - followed by detonation), I did notice that the top of the rod bearings were showing their discontent. Clean up the tops of the pistons and get a new set of bearings and it's all good!

That's WAY better than the trip to Speedworld where I blew a quarter-sized hole dead center in the top of one of the pistons! hehehe

Ground straps? No big deal.

I'll watch for you out there!

Hey Blaine, just ordered some race plugs per NGK techs suggestions. R5671A-7 for 10-15 lbs boost and R5671A-8 for 25 lbs boost. CU at the track

I would put a -9 or -10 for 20+ lbs. of boost, never a -7 or -8 heat range plug I run -7 and -8 in my pump gas low compression street motors at 14.2 AFR and leaner at idle and part thottle AFR

We run a -9 with 15-16psi and 8.8 static compression. 406 cu in small block.

That is one great running "land yacht". If I wasn't so old or stubborn I would love to play with a power adder. I would probably have to go the procharged route as I still love the competition of racing and I think that makes a more consistent combo. Maybe someday but nitrous will never touch one of my cars.


1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27

Livin and lovin life one day at a time

This blower motor is a big learning curve for me right now, which equates to - not very consistant. Just hope I don't "step on my crank" too severely while I'm going to school .

That's why I would not be making too many changes to what you have. Those plugs are real close to being spot on. You should really only make one change at a time. If it was my car I'd swap plugs and make a pass to the shift into hi gear. Turn it off and check them. Adjust the tune up in baby steps to dial it in. Then I'd detune it a little with a little less timing and try to enjoy beating on it for a few years
