New time 11.81 @ 117 CT26 powered 7M NEW RECORD!!!

Saw the thread today and just read all 11 pages. I was 50/50 on whether or not you'd break the CT record, and damn you made it seem so easy lol. And honestly, I'd never thought a CT record (with boost only) would be broken with the A340E! If ride of the month still existed, I'd be damned if your car weren't nominated.

Well I got it all back together and running, ran great and made good power! I fucked up hard core because I was rushing and forgot to tighten the CPS bolt after I set the timing. Ended up running for 3 days, CPS advanced it self as much as it could go and melted the no 2 piston. Everything is out and pulled down to a bare block again so I can hone the cyl and throw new pistons in. One small mistake cost me shit loads of labor. Oh well what is done is done.
On to the next one!

Sad to hear that Bro. Get Some rest if you can.
Just wait for the retorque on the MLS headgasket before you go hard next time.
Preignition sucks + issues are a part of this Game.
Being Fast is worth it. (LOL), Some How...

No need to retorque on a MHG with ARP's as long as the head is not annealed and ultra lube is used.

This is not good advice here, it is always good practice to do a retorque. For more than a few different reasons. Metal HG or not.
You dont need to re-torque. Arp recommends that you preload the bolts before putting them into service.
depends on if you mean to loosen them and then torque to spec, or simply check that the torque has not changed?
I have never had an issue with head studs loosening up, built many kinds of motors and several 7M's with out ever doing a re torque.
Anyways, Machine shop tomorrow to do a hone and deck a new head, lap valves, valve lash and then put it all back together tuesday. This time Ill make sure I tighten the CPS bolt......

I never had an issue with metal HG (HKS stopper type) until it was not retorqued. It's more the gasket settling in and squishing out than the bolts loosening that creates this issue. A retorque IS recommended and certainly will do no harm. But most certainly will do some good. Do the retorque, and performance shop that knows these engines will agree, it's just good practice.
We have a 5000sq ft shop dedicated to performance and High HP turbo cars. On a composite head gasket I would recommend a re torque as the gasket will compress and alter after a few heat cycles. Only time I have seen studs loosen with a metal head gasket is if the head was overheated and the aluminum is annealed causing the head to compress when it heats up.
Either way you can do it for good measures, but on my motor I see no need to!

I use a paint pen to mark bolts that i have torqued. Pretty much ever nut or bolt had some kind of coating. Either oil, Arp lube, Locktite, or antisieze.
Of all the performance shops or race teams i have seen the only time head bolts get touched again is to rebuild the engine or reseal the head.

Didnt mean to have this Retorque Suggestion take over your thread Devin. It belongs in another Spot. Who will look at it there ? LOL
Anyway Good Luck with this Rebuild...7MFTW
Headgasket is the least of your problems. I Love what you doing with that little CT26.

I agree, not the place but since the man here has such an awsome and well read thread due to the stunning numbers I thought I'd add it in. As I said I blew my HKS metal stopper type hg. But others milage may vary. I was pushing 28psi through it at the time I seem to remember.....or was it more. LOL
Well got the head machined today and all put together tonight. Had to take .008 thou off the head to get the grooving out of it, then another .002 to get a corroded spot off in the back where the coolant jacket is. Took a total of .010 thou off. Lapped all the valves, checked guides, installed cams, checked valve lash. Intake set to .006, exhaust set to .008. Filled each port up with alcohol and made sure all valves were sealed against the seat.
Everything checked out good, should be throwing the bottom end and everything thing else on tomorrow night. Then dropping it in wednesday!
