Strange, I’m running a tremec magnum xl with rxt 1200. No, shims except on the starter. Is it grinding on shift or especially notchy. I know my second and 3 can be pretty rough when it’s not warm but I’ll attribute that to the fluid I’m running. Smooth as butter when warm Sent from my iPhone...

One of the first things I did after adding a supercharger when I had the mt82 was go from 3.73s to 3.31s. IMO, On a boosted car it’s a great ratio. 3.73s would be good if you were doing a n/a build. Sent from my iPhone using svtperformance.com

It’s the hellion down pipe to 3” o/r h-pipe. I don’t want the car loud all the time with a single chamber resonator. Already planned to disconnect the hpipe, the point of the post was to see if anyone else has experienced boost limitations on a chambered muffler. I’ll be running qtp cutouts for...

I’m running a hellion 6266 setup with an ams 1000 boost controller and the car seems to be limiting boost around 18psi. It has 3” hpipe with gt500 mufflers. Does this sound like an exhaust restriction preventing me from making more boost? The car makes over 1000hp at 17 psi. Sent from my...

Anyone here figure out how to run a true boost by gear setup with the tremec magnum xl? Car is currently setup to trigger boost change by clutch but I would much rather have a true boost by gear setup. The clutch way only allows it to click up to the next higher boost setting and only option to...

I debated on grabbing the 64s but, it being a 6 speed I opted for the 62s. May upgrade them dependent on if I go powerglide. Are you running a air to water ic? If so from where and what kind of iat’s are you seeing after a pull? Sent from my iPhone using the svtperformance.com mobile app

I’ve got a tremec magnum xl currently. Will be running the airstrip with it and see how I like it. May go to a power glide, depending on how I like it. Sent from my iPhone using the svtperformance.com mobile app

The car has a built\sleeved motor running twin 6266s. Finally, the car is getting dialed in and made 705rwhp\705rwtq on 92 octane @11psi. The car is just getting tuned on e85 but it did make 780rwhp/780rwtq on it with the same 11psi but with +3* in timing. I’m looking forward to see what kind...

Yeah, I was curious what others are making on 92 at what boost mainly before any knock. I’m expecting at least 1xxxrwhp on the e85. They’ve been turning up the boost little by little, I believe the wastegate pressure was 5psi and it made about 515rwhp. I would like to see about 700rwhp on 92 but...

So as the title indicates, I’m trying to see how much boost to run for different fuel types. The car is a 2013 5.0 with a built and sleeved bottom end with forged Manley pistons and rods. The compression ratio is 10:1. The car has a Hellion twin turbo setup with 6266s. Car is in the early tuning...

Current situation, motor is being built to be 1500hp capable with a 11:1 compression ratio. Planned to run twin 62s for a goal of 1200+rwhp. Seem about right? Anyone know what the twin 62s and 57s max at on a 11:1 motor? I plan to run it low boost in the 600-700hp range on pump and 20-25psi on...

In need of a 5.0 engine block or possibly a built shortblock.

I installed the magnum xl but need some info on the wiring since no diagrams were provided. Can someone identify the 3 connectors on the mt82 vs the tremec magnum xl? This is what I figured is on the mt82. 1) Skipshift solenoid right side near shifter mount housing. 2) left side rear...

Looking for a good mt82 no issues. That means perfect shifting piece with no grinds at any rpm, thanks

I've noticed after about 2 wot pulls, my head temps will go 230+. It went up to 250 once before and normal driving is about 205-210. Never really paid attention to it before but recently noticed. What kinda of head temps are you guys seeing after wot runs? Boosted or not

Well, its about that time to step up to the next level. Car currently has stock motor running at 13psi with stock headers on E85. Car should be about 750rwhp at the moment but I need to do a magnum swap and would like build the motor at the same time. I've read that I should expect 900+rwhp with...

As the title says, anyone know a place in Cali that builds mt-82s? My third gear syncro is seems to be jacked up from when I was on the stock clutch. So at the minimum it will need 3rd gear syncro, but while I'm having it repaired I would like to have it beefed up if possible. Anyone know a good...

Anyone have or know where I can get the spring chart for the wastegate that comes in the beefcake kit

Ive noticed recently im having problems with 3rd gear. I was racing a Bentley Continental earlier and my third gear was grinding trying to get in when the clutch was to the floor. This has me worried my trans is gonna take a shit. I thought maybe it was my fault and maybe the clutch wasn't fully...

My car currently has 21k miles on it. I'm going from a 3.73 to 3.31. Do you think I should replace the bearings when I do the swap or the old ones should be good? I just don't want to spend extra money if I dont need to. Another question is what is the latest and greatest for rear diff fluid...

I know we have a lot of track veterans here so I'm kinda curious what you think my car will run at the 1/4 compared to my expectations. The car 2013 5.0 -Mt82 -3:73s -MT et street pro on 15" -Paxton @ 9.7 lbs wastegated 3.33 pulley -o/r h -JLT cai -e85 -eibach coilovers -bmr...
