Finally got the new combination tuned, and the results did not disappoint: 540 RWHP @ 6200 RPM and 492 RWTQ @ 5000 RPM. This was at 13 psi boost and 11.6 AFR, with tuning handled by Walsh Motorsports in Wixom, MI. For comparison, the old SVO-based setup produced 375 RWHP and 415 RWTQ.

The parts I used for the rebuild were:
Teksid block with Big Bore kit (same as before)
Forged rods and pistons (same as before)
Forged crankshaft
9.5:1 static CR
MHS Stage 2 PI heads with +1mm SS valves
MHS Stage 2.5 PI cams
Tork Tech Terminator GT kit
VMP TVS2300 supercharger
Accufab oval TB
60# Siemens Deka injectors
SCT BA-2600 MAF
Boost-A-Spark and Boost-A-Pump

I worked on this update from right after returning from the Epic Drive until now. Would love to do some spirited driving, and better yet visit a dragstrip, but winter has arrived early in Michigan and the car needs to go to storage very soon.

Congrats, can't wait to hear you smoked a modern Mustang.

What headers are you running? 1 3/4" Kooks?

I have the smaller diameter Kooks with the 2.5” collector (I think 1-5/8” tubes).

There is a particular modern Mustang I intend to smoke when conditions are right: my son’s 2015 GT Performance Pack which has been thoroughly modified but is still naturally aspirated. That car runs consistent 12.2 quarters. I’m hoping to run very low 11s, maybe even a 10.9 on drag radials.

Nice!

Is this still through the automatic, or did you do the 6-speed swap at the same time?

If we were bench racing, that car is easily low-11s. All that remains is to get that timeslip and make it official when time and season permits.

This is through the 4R70W. I ended up not doing the manual swap this year. Made that decision on mid-July when I realized very little had actually gotten done by then.

Nice job, Mike. Tell me more about your Teksid Block with big bore sleeves. I would love to get my hands on one of those.

Your consistency will be at it's with the automatic transmission.

I bought the Teksid block off eBay about 11years ago. It was from a late Mark VIII (96-98, can’t remember which year). I looked at stroking or boring for more displacement, and the recommendation from the guy who was going to build my short block was to go with the Big Bore kit from Dalton. That cost more than a stroker crank setup, but was supposed to be better for piston strength and ring sealing. I’ve had no issues with it whatsoever over 11years and about 19,000 miles of operation.

A big bore motor will also make more power than a stroker motor of equal displacement due to the larger bore unshrouding the valves, which allows more flow out of the exact same head.

Big bore + Stroke = :D

You'll easily smoke that Mustang. Shame on you for picking on your son. (LOL)

Low 11's or a 10.9 are easily within the realm of possibility for your build.

My car is trapped at the tuner. It is 30 F and snowing here, and there is no way I'm attempting the drive on summer tires with 540 RWHP!

Thanks Matt! ... yea, that's it!

Yea, it'll have to wait for better weather; such is the nature of Michigan in November.

I plan to have some new track numbers and video of my car on Sunday. We're heading to Rockingham for a private track rental. I'm so excited. Not to hijack your thread but, I plan on embarrassing some modern Mustangs myself.

The weather's supposed to be great here in the Carolinas this weekend. It's hot-as-hell-miserable here in the summer but we make up for it in the fall and winter. :D

Trunk,

No problemo! Somebody suggested to me that I should pack up the T-Bird and head South in search of an open dragstrip. Sounded like fun , but we've got a bunch of things going on this month, in December, and into the rest of the Winter.

BTW, I have a scan of the dyno graph, if somebody can help me figure out how to post it!

Select "GO ADVANCED" and you can drag and drop the dyno graph into the "Drag and Drop File Upload" box.

I think you can also use this feature from the basic posting box. Just look for the "Drag Files Here to Attach" box.

Simple as that.

Here it is (I think). You'll need to rotate the image after you open it.
That's a NICE torque curve, IMO!
