What you're doing is the epitome of bulletproofing. You run what you have until it breaks, then fix it better! Way to go!
Torqstorm.. let's see how it does

The lower compression doesn't seem to have changed much.
Still trapped 127mph @7100ft da this weekend. Converter has about 20% slip now. 6500rpm, 28" tire, 3.55 gears 1:1 final gear in the trans.
I seem to have figured the fueling out for the most part. But in the top of third it gets really fat and starts to stumble. Not sure if my fuel bowls are getting too much because of the boost reference regulator? (Just a theory) or maybe the boost reference power valve is hanging up?.. I know on the return road it also ran super fat (10.0 gas scale). But if I park it for a while then fire it back up it's back to normal 13.0 idle, 12.8-13.0 cruise.
Someone mentioned spark blowout. But I dunno. Plugs are gapped about .028 and it's about 6-7psi.

If you run 10 lbs. mani. press you need to have a regulator that increases fuel press. , with 10 lbs. boost on a blow through carb you need 17 lbs. fuel press. at boost.
I swapped over to my pump gas carb. Drove around for hot august nights and overall beat the piss out of the car.
first pass on the next track day to see how the gas carb works…10.0 afr at wot. 2nd pass, pulled some jet.. 10.2-10.8 afr….. popped a head gasket again.. same spot too. I have some SCE titan ICS copper gaskets on the way and I’m gonna drop the heads off to be surfaced. So hopefully the fresh surfacing and new head gaskets help.
Tbh I expected the head gaskets to give up the ghost. They’re the felpro 1008, honestly surprised they even survived the first 2 track outings.

1008’s at how many PSI?
That’s what they say about me and my head…. Not so much my cars head….

You've
Have you checked block for straightness, have you looked at block deck thickness in this area? 10 lbs. boost isn't anything. also do you have a boost retard? just trying to help.
i,d also look at spraying with alcohol in frt. of supercharger even if afr. is good, cools intake charge to eliminate detonation. The 1008 has a fire ring around cyl. .

Two atmospheres are better than one
1008s are junk. You need mls gaskets.
@Toluene56 are you showing any signs of detonation on the plugs? I bet it’s rattling and pushing out the gasket.
10lbs of boost on 10.5:1 compression on pump gas is a whole lot more than what you are saying.

I use SCE ProCopper Head Gaskets. I O Ring the heads and cut receiver grooves in the block.

Nope.. plugs look perfect, no speckling or anything. I know the heads are damaged from the first detonation I had with high compression. I have a machinist straight edge, block looked fine, but the heads did get a little torched. I figured this was going to happen, but it got me through the major events.
I think the rattling sounds plausible, it only happens with a full 1/4mile pull. So I'm also looking at an intercooler setup. Probably a2w for packaging.
Yea. Already have the new ones.

We'll see how these do after I get the heads cleaned up.

normally copper gaskets require o-ringing the deck. They’re also not great for street use. I’d recommend a pair of cometic.
..... these don't require o ring.. they have a fire ring built in and seals around the water ports.
I had cometics. They torched during the high compression setup. They're backordered for months. So whenever they're readily available again I'll order some and keep them on a shelf.
The .039 cometics are in stock at summit. I ordered and received a pair last week. However I do believe the titans to be stronger so you’re likely on the road to success! Still surprised to see the 1008’s all pushed out that way. I assume you’re having the heads resurfaced also? Head studs?
They don't have any cometics available. I live down the road from a summit racing. Everything says Nov 17. Doesn't mean it wouldn't be quicker, sometimes they exaggerate the lead times.
Yes it has headstuds. If the machine shops can do a basic resurface in a reasonable time frame. But so far everyone says they're months out and to be honest I don't trust any of the machine shops in my area. But I'm still not putting them back without being surfaced.
Might have to go on a road trip.
Wow you’re right. Just checked and the gaskets I ordered are out of stock. I guess I got lucky! Maybe you can ship those heads out to a trustworthy shop?
Yea. I'll make some calls and see what can be done or what's available.
Engine is back together. Had the heads surfaced locally, luckily they did well. Checked the deck surface and cleaned meticulously.
Added some sce titan ics copper gaskets.
Retorqued the heads after initial heat cycle and added water. No water leaks (thank god).
First drives show the car back to normal, no weird overheating or anything.
I was able to make it to the last track day of the year, this time on e85. Now I know the problems with this e85 carb. I should have it dialed by spring. Maybe earlier if I'm lucky and take it down the sea level, that would be fun.

Sold the torqstorm to a like-minded individual in cali. His 4spd car should be a blast with it.
swapped to a turbo last year.
Goodbye Torqstorm, hello Spoolius Ceasar
