Thread: Redline Heavy shockproof

I will be changing the tranny fluid this weekend. I will be switching to shock proof from mt-90. I have run shock proof in my turbo car since I put the car together in and its still in one piece. I would like to see proof that it causes hp loss because I made 342whp at 15psi on a gt28rs. Hoenstly its only thick when cold and the fluid does heat up quick. I will take all the protection I can get I have broken a b14 tranny stock.

Almost forgot, and you probably know this....

Upgrade those tranny/motor mounts. Window weld, Prothane, whatever..... It will help to keep the (crappy B13/14) tranny case from twisting and flexing.

As far as I am concerned, anything to help keep the B13/14 trannies from destroying themselves is absolutely critical. More critical than 5 horsepower, unless you are a quarter-mile freakazoid, can rebuild your own tranny, and simply have to shave that next tenth of a second.

I know for damn sure that when my B13 transmission inevitably takes another dump, that that son-of-a-bitch inferior, piss-poorly designed, under-engineered, peice of sh*t transmission is getting replaced once and for all.

Not that I'm opinionated on the subject or anything......

I have always used shockproof and have had polyurethane shore 90A filled mounts since I have turbo'd my car. NEVER broken a transmission yet, currently putting down 334WHP and no problems as of yet.

I just did a VE swap and personally put in the lightweight shockproof, only driven a few times so far with that in it but seems to be fine. I might switch to the superlight weight depending on how it feels when it starts warming up.

FYI I used heave shockproof and works fine even in 30* weather. I am sure it doesn't help with drivetrain loss because it is so heavy etc.. until it warms up but I haven't had any side effects.

for the VE guys go with the mt90, its GL4 rated, which does not eat brass and is recommended for our gearboxes. Not ideal for turbo of course.

I have the same experience. No real issues with the heavy shockproof except every now and then when I first start it its a lil hard to shift. I have the stronger p11 box which is why I wanted to try something a lil lighter if possible. But this stuff has worked amazing thus far.

I think the decision is more based on how you drive. HP comes into play, but if you tend to be more gentle of a driver compared to more aggressive then you will have better luck - i.e. do you fully let off of the throttle between shifts or do you power shift? I make sure the car is fully in gear, then get on it.

I run SP Heavy in my VE car because it is built for a road course. I wasn't concerned with a couple HP loss since my car (when driven) gets abused on purpose. I drove my VE yesterday and it was 18*F when I pulled out of the garage - it was a little stiff.

The warmer the temp the less you can tell a difference. I figured it was better safe than sorry. When I change my clutch in my DD G20, it will probably just get MTL or MT-90.
