Apparently, Michael is no longer with ISSPRO (in the last couple of months I'm told). Anybody know the PerforMAX line kinda deeply?

Somewhere, I thought I've had somewhat in-depth talk about setting my waste-gate via math using drive-pressure, boost, etc. I've searched and can't find anything about such. Ratio, Back-pressure, etc shows nothing. Can anyone help me by presenting the math to show what the ratios are with given...

Hope everyone got some time off for the Labor Day holiday. If you didn't, thanks for holding the fort down. ;) I recently broke my block and with finding a replacement and finally having it machined, I got on with cleaning it up. Chased all the bolt thread stuff. Bottom-tapped the head...

I'm in the glacial-slow process of building a new 12v. While waiting for back-ordered stuff, machine-shop processes to occur, etc, I got to wondering: Would it perhaps be wise to, as a Predictive-Maintenance thing, replace the studs I currently run? They are of the A1 brand as purchased from...

Just so it's been covered. ;) I recently cracked/split the block. Heavily on the passenger's side of the front-most main-bearing webbing. Cracked in the same(ish) spot on the 2nd main-bearing webbing. Cracked through the oil-pump recess. From there all the way back on the side of the block to...

So, I broke my block and am pulling stuff out of it in hopes of reusing it. I got 188/220 steel cam and 24v lifters from Zach in Feb of 2012. I'd been running his 110 (?) valve-springs with his 1st stage HD (whatever) pushrods. Anyhoo, pulling the cam out this afternoon and standing back and...

I've got to get new pistons (and a replacement block :bang). - I have what I think is a well flowing head (195/220) that includes swirl-inducing reliefs. I've run the head for a good while now with the stock/OEM '93 pistons (narrow/deep bowl?) and the associated 145* nozzle spray angle...

Engine block's lube-oil pump recess . . On the way in to see which cylinder/rod-bearing is stomping around. Crap. :doh:

Well, after 295,502 miles over the course of 27ish years, I believe I've a rod bearing that's had enough. It's as good a time as any to freshen the short-block. The current heap amounts to a stock/OEM 1993 short-block with 145* pistons. The head has some swirl inducing reliefs in it that drop...

On a RH controlled trans, is it possible to, by way of a switch, engage OD and be able to start a dyno-pull at a very low wheel-speed? - Or would the Throttle-Valve ultimately override and downshift? I've got the one worm-track in the VB blocked so as to allow locking the converter in 3rd or...

Greetings Earthlings. While in the midst of building a Frankinsteen transmission, I've the choice of a trans fluid pump from a 46RH and that from a 48RE. 46RH . . . 48RE . . . . The build consists of a: - OEM 46RH overdrive case and output shaft (so as to mate to my existing OEM...

I'm fixing to upgrade/refresh my heap's automatic transmission. :) I got to thinking about what I might change about the current transmission's valve-body and got to thinking about where's the best shift-point(s). It's been my understanding that: You want the shift-points such that when you...

I'm dicking around under the hood again, and converting the 1st gen heap to a lock-up converter. VE fueled so the power might be up to 900 ~ 1100ft/lbs @ around 500 or so HP to the ground. Tops. . . . . . . on a good-air day.:blahblah1: ;) I'm currently running an SFI rated stamped-steel...

Somebody asked a while back that I post something on my heap as of late. It's fixing to snow outside, I'm bored, so . . .. bear with me. It's not as hot as many here, but it's what I have, it's paid for, and I built it myself. I bought my '93 W250 CC new in late November of '93. Took to playing...

Greetings Earthlings. I bought my 1993 Dodge/Cummins W250 new, in 1993. Right at 175,000 miles on it now. A few years after buying it, I broke a tooth off the pinion gear in the rear OEM DANA70 (dunno how) that includes the OEM Power-Loc differential. I replaced the ring & pinion and have...
