I was at the limits of the engine with 500rwhp and 450 torque. Everything was done with reliability in mind as I plan on keeping the car and driving it hard for as long as I can.

I believe I’m in a similar spot with mine and I’m curious if you kept the stock CR or went up/down any?

We used forged pistons from DSS which resulted in a CR of 10.12:1. 6BD23B2D-6707-44A4-A38A-A32B5F7F3987.jpeg

Negative.

So, I was cruising in 5th datalogging on rt1, 60-ish. For the exit, I popped in neutral, idled at 1000 to stop. I put it in 1st to make my turn, hear some scraping sound. Let the clutch out, sound stopped car will not move. Pedal feels like its over adjusted, no play. Did I mention I dont have my phone with me? If it moved, it would have been no issue driving it back home. I have never seen a clutch go out like that. And I had the trans out a few thousand miles ago, clutch still looked almost new. I dont drag race, so there is no abuse on the clutch. I am baffled what it could be. Its in the spot where I will be pulling the trans, just time from here. And the auto adjuster has been replaced with adjustable cable and fire wall adjuster. I thought about just unhooking the cable and see if it would move, but said fuck it, just went and got it with my trailer. I now own a 12 v winch. lol

Its not a t5 btw, it was auto originally. I swapped it with the 3550 swap kit.

Sorry, (reading comprehension) I misunderstood your comment! I thought you had said the clutch cable broke.

New headlights and S550 brembos are on from yesterday, hopefully sorting clutch issues today and it will be on the road for a proper datalog and tune, kinda hyped ngl.IMG_4279.jpg

Pulled the 3550, found my clutch issue. What a way to spend the 4th!
The friction material came off the disk. Wonderful. Well, it has been in there for 15 years. But I was expecting to wear it out, not for it to fall apart.

Fixed a loose exhaust bracket and adjusted the tailpipe. Love my lift!

Unloaded car from the trailer and back to the garage it goes. The Drags didn’t go that well. The rear end held up and that is great but I can’t keep a belt on the engine for a complete pass. Four runs and threw the belt three times. Managed an 11.60 after going up in smoke on the line. I have most of what I need to step up to an 8 groove belt so that is what I will try next.

I have recorded 17.5lbs with the pulley setup I’m running. The alignment looks good on all the idlers and accessories. I think the problem exists with the tensioner. The belt appears to run on the edge of the pulley and I’m sure it ran centered when I installed it.

The belt runs on the outside edge of my tensioner pulley also. Currently, I have the DOB Frankentensioner setup. The only way this is possible is if the inside tensioner is bent/ warped. It is one of the things I need to check out before I go from 10 pounds to 12.

Frankentensioner
I ran a different pulley combination with a Frankentensioner at 16lbs and had no problems at all. When I tried for more boost with a 10% overdrive I hit 18lbs but must not have set it up correctly because the tensioner broke. I will be more diligent in my setup with a new Frankentensioner and 8 rib belt.

Received 4 brand new Cooper 255/45/18 tires, which will get installed on the wife's factory GT500 18x9.5 wheels and will probably get used twice a year: to and from the state inspection place. Tons of tread, and they will fit front and rear on both cars, her Shelby and my GT

Can't wait to see how well they hold the 650 rwtq of the Shelby ... LMAO

Finally got around to getting the front end realigned this morning at my local Ford dealership after the FR M-3075-E FLCA kit installed some 3 yrs ago & OEM Bullitt springs installed a few months back (noticed that a 1/4" wide wear line appeared on the outer edge of the inner tread shoulder on both front tires.....indicating front end had excessive neg camber from the FR M-3075-E FLCA's (slightly longer from inner bushings center to center of ball joint than the '09 OEM units I replaced......will make note of this going forward for future references as I assumed that this length was std across the S197 chassis. I have the FR Caster\Camber bolts installed & had already marked cam alignments prior both installs so had set all back to alignment marks, so I figured all was in spec. Car drove fine so all was good.........NOT!). The tech told me that all else was good except camber was too far neg.......then I got chewed out for over tightening the cam bolts causing him to have to pull both front tires off & remove both calipers out the way to break them loose to set camber (so now I know my HF EarthQuake 1\2" Hi TQ Cordless Impact has no problem setting the 166+ ft-lb TQ spec for these bolts, which is what I used to tighten them then checked w\ my TQ wrench to ensure they met proper TQ specs.....hella easier than trying to get enough leverage using my TQ wrench while holding the cam bolt on alignment marks to tighten them. Yeah, I'm that well known there.)

Car now tracks straight as an arrow but is still very responsive to steering inputs so she's ready for the road now.

Exactly how much negative camber did u have...that wore out the fronts ??

Can't say......I didn't ask the tech for the sheet, but I confirmed his statement by checking the caster\camber cam alignment marks I had inscribed on both caster\camber cams & strut\unibody from the last alignment done by same tech prior FLCA changeout & spring changeout......caster marks were still in alignment, so caster wasn't touched thus was still within spec. Both inner\outer tie rods are good & tie rod lock nuts weren't touched so toe wasn't touched. Both FR M-18183-C upper strut mounts were still mounted in same default position w\ notches pointed outward.....only the camber cams were out of alignment thus were the only settings physically changed. Both L&R camber cams were rotated to input positive camber to spindles thus negative camber was excessive according to spec & can only assume that when camber was reset, toe corrected back within spec off the camber reset. From the camber cams current position, camber was fairly far negative (cams are almost at full positive rotation now so around +1.2* to +1.3* of the full +-1.5* adjustment range of the FR M-3B236-A kit to bring both sides back within spec). I have remarked new alignment position on both L\R camber cams to strut for future reference.

Exactly how much negative camber was there prior I can't say, but the wear line appearing on edges of both inner tire shoulders are a dead giveaway of negative camber\toe out being excessive. Rest of tire tread is still good on both front tires. Can't see the Bullitt springs causing this (front ride height only changed 1\4" higher) but I can definately see the FR M-3075-E kit causing it if they're slightly longer than the OEM units they replaced as that will increase negative camber & potentially cause excessive toe out.

I didn't make any special alignment requests since this car is mostly a cruiser so assuming that the tech went w\ OEM alignment specs for a '09 GT.

Car tracked good prior realignment, but it tracks even better now since so as far as I'm concerned all is good now.

Added a Paxton Novi 2200 package (beefcake special) to the recently purchased 14 GTCS. Made 589rwhp/495RWT on 10.5 psi boost on a 90+ degree day. Lowered 1.5" and tasteful mild drag suspension mods as well. Of course OPG and Crank timing gear as well. Some other goodies also. Pics when it gets finished. Had a glitch on the front caster/camber strut plates. Too noisy for a street car. Going to a stock GT500 strut mount.

Now you have to find another 11HP and 5TWT.
