As above what's the limit of a 5speed?

Also what is the strongest Box to buy?

Thanks ryan

 

Ask Martyn at engine tuner think he ran 500+ on a 5 speed box!

 

I ran 402 on a ty52 box ty54 box even stronger

 

Ran 430lb/ft on a 5 speed before it have up !! It had 120k on it before 2nd gear gave way , around 360hp

 

As above around 360bhp on the Type R DCCD box. Newage 6 speed is a good upgrade path

 

My exploits on the original V6 5 speed are well known. I really pushed my luck running in excess of 550bhp and 520lbft through it for some time before it finally threw in the towel.

In my experience you'll be hard pushed to beat the stock Hawkeye 5 speed for reliability as I know of a fair few of those running decent torque without issue.

 

My hawkeye WRX 5 speed gave up the ghost running 389bhp/400lbsft after gearbox rebuild and only after covering about 3k. I don't drive aggressively either.

 

How many miles did u do

 

Ty754 P1 box 18k miles at 440bhp/ 380ftlb. Still working flawlessly when it cameoff.

Usage- I'm not interested in drag strip stuff or hard launches - more fast B road / track use.

 

6000+ on the road as well as a full season competing in the pro street drag series at Shakespeare County Raceway. Following the end of that season it broke the 3rd 4th gear cluster. Replaced that part for £200 and did another season on the same box.
On the ratio of runs to breakages it was better than the PPG I replaced it with before going 6 speed.

 

It's not power that destroys a gearbox, but torque.

 

Some very surprising figures for 5 speed boxes being put about

 

+1 trust. Lets see what my p1 box does with a gt30 lol

 

Running around the 300bhp mark on my wrx box. All seems well.
