ok im building a drag/street car car will make 850whp on pump and im going to get a pump gas tune of 450whp or so ...now my question is if it will ok to run a ppg pro race gears on the street ...plz if anybody has or had a dogbox tranny plz give me some info on what it was like

 

It was loud. It was not smooth like butter, it was more like slamming gears. It worked very well. Super Street also did an article on dding the dogbox but I forgot which one was it.

 

if you know what your doing it won't be too much of a problem.

 

I need to know this too... how reliable is it on the streets?

 

You are going to make 850whp on pump....ok.

I had the PPG box in my street car. I just cranked the music a little louder if the whine got too annoying. Shifting the car is a little different obviously with the box and you can't baby it. As far as how long it will last....don't know...sold the car before it got about 100 street miles on it.

 

There was a video on YouTube which i cant find right now of someone at PPG showing you how to shift properly using their kits on the road.

 

Dogs don't have 1 iota of a correlation with a STRAIGHT CUT GEAR SETS inherent noise making. I have a synchronized STRAIGHT CUT set, its loud... I like it....


Dogs on the street??? I answer impractical... Some will argue "But Ive seen this video or that or whatever"... Well, 90 percent of the time not 1 of the people answering has NAY experience with running a true dogbox on the street.

Im not going to even get into why its impractical for a true streetcar. Read more. SOunds like you need to anyways, Im just sayin.

I know plenty of people that have had issues with dogs and the required method of shifting on the track in the few shifts racecars see (everything from strainguage issues, to incorrect throw adjustments, to dogs being bad from lazy shifts... which wouyld KILL them in a street car)... Including the PPG set. Its not manufacturer specific, its design/application specific.

Compare that to the literally the 100s of 1000s of shifts a true street car makes every year....

 

Dog boxes can be used on the street if you know how to shift correctly and your prepared to strip the boxes for inspection a hell of a lot of the time.

I have worked with companies that build their own kits and supply them in Europe for Evo's and they use them fine on fast road cars but do advise a 300km (yes 300km) race distance for teardown and inspection on every box.

 

CLIFFNOTES: Completely impractical for a street car

 

You will just be dropping the tranny alot. Harder dog rings
last longer but destroy gears. Softer dogs will go fairly quick
but wont mess up gearsets. I had some hewlands last 30k miles
and some last one day at the race school i used to work at.
If you shift hard and fast expect them to go fast. The sequentials
go through them faster than h patterns also.
