Kowboy thank you for taking the time to write your experience with the S363. We're going to try a 363/68/.91.

65 psi, 3200psi, iirc around 40% duty cycle. No exh leaks, no boost leaks. As I see it the 80mm turbine sucks for spool up.

Helping to build an all around farm/tow vehicle. It's a 2000 F350 that has 4.10 gearing, locally built 4R100, reg return, Tymar intake, 200/30% hybrids, SXE 364.5 w/ 80mm turbine and .91 housing, and a Hydra with Jelibuilt tuning. That's how the truck was purchased. With a hot street tune the...

I don't see how a core shift on a rough casting would lead to a finished bore being out of line. It would either clean up or not. I would say bored out of line better describes this. It would be interesting to know how Navistar actually machined these and what the actual true position on the...

I've been running a 190amp DC Power alternator going on 10 years with no issues at all.

I got a set of tunes from Brian during his Black Friday sale and at least with mine the trans shifting is nearly identical to Cale's tuning and it drives very well. BTS trans though. Those are the only two tuners with whom I've gotten good trans strategy from. I would have stayed with Cale...

How does the 6.7 starter compare to a genuine Denso unit? Working on a truck for a friend and the original starter is way past due for replacement. I can get her either one for about the same price.

Tired of tripping over this stuff and want it gone. Around 101K on all parts. Crankshaft $30 Front Cover $50 Camshaft $50 Cam Gear $25 Cylinder Heads $50 for the pair The heads have valves, springs, injector cups and a few hpo/fuel fittings. Exh manifolds are there but are...

Mine is in the oil filter housing.

John I'm trying to reply to your message but you need to clean out your inbox.

I know the pump fitting is M16x1.5 as I made my own. Not sure on the booster, I kept the stock lines on mine. Pretty sure Lee Power Steering can hook you up with the correct fittings if you give them a call.

Pulley is part of my electric vacuum pump conversion, look for my other thread for more info on it. Booster is MC# BRB-37

Since converting to hydroboost my vacuum pump only worked the HVAC controls. For years this worked fine and I never experienced any issues with the mechanical pump. Relocating my power steering reservoir next to the a/c compressor led to me looking to make some more room in this area. Taking...

Wanted to update this thread with a change I made concerning the p/s reservoir. The one I custom made worked well but was just too far from the pump and resulted in a loud buzzing or hum in the cab. Looking things over the only real alternative was to mount something next to the a/c...

Besides being quieter there is no blue haze on startup with the hybrids. Power wise feels about the same. EGT's are considerably cooler across the board in all situations. If this were just a street truck then the 175/100 would have been fine. But for towing there is no comparison the...

I've run both 175/30 and 175/100 and have to say that going to 200/30 hybrids has been a night and day improvement. All 3 have run on the same setup where only change was injectors and the tuning for them. Tried tuning from most of the major players and just couldn't get consistent results...

If they are encrypted they have to be for your Hydra s/n. If they are not encrypted then yes you can use them.

Billy from what I've read about others doing this mod is that if you keep your rear drums then you keep the stock smaller master. I spoke with Edward at VANCO about porting a hydroboost unit. He said it was unnecessary even with an upgraded p/s pump unless you were adding hydro assist...

Here they are, 1026 miles on them since last rebuild. No issues at all. $1100 shipped w/ a set of cores required or $1300 shipped no cores required.

Just to update this I got the owner to pony up for a genuine Motorcraft master cylinder and that fixed the problem. I generally believe Raybestos to make a good product but something was obviously not right with the one he had previously purchased new. Garbage Mechanic I got the gauge and...
