GTB1756 limit?

The chart on Darkside website says 230bhp @ 31psi.

 

Mine was initially mapped and went on the rollers and did 240 bhp and 350lbs torque, it was over boosting and smoked a lot though, I think 210-220 bhp is more realistic on a low smoke map @ 2 bar.

Not a clue mate. Guy I bought it from couldn't remember exactly what it made or what boost it was running.

If there is enough headroom in the turbo to warrant it I'll stick an uprated clutch in and remap for more torque. Didn't yours do 235 and high 300s?

As above imo

Injectors aren't needed for a 1756,and would be a waste of money and make the car a horrible smoke belching thing :)

It is a GTB not a hybrid.

I'm thinking replace clutch with uprated item, new dmf and then remap for the extra torque that it will hold.

I know the current map is a clutch "friendly" one, so for the sake of argument say it's 300ftlbs. If it was pushed to 360/70 that's a 20% increase in torque. Surely that will be noticeable.

Thanks for the info folks. I'm leaning towards an xman clutch and a new sachs dmf. doesn't sound like my turbo is going to go an awful lot higher than it currently is so anything more extreme clutch wise is likely to be wasted unless I went for a bigger GTB.

People saying their at the limits is all guess work. They don't drill and fit turbo speed sensors to monitor the rpm their running at then use the compressor size to calculate air tip speed. Or calculate the ve of the engine, calculate airflow then plot it on the compressor map.

It's all *******s :)

Iirc the person that remapped it said it was at its limits of around 2.1 bar or something as I was disappointed with the figures.

The GT1752 hybrid remapped better than the GTB did.

You mean the one I've just sold ha ha :)

Can you remember the figures as Davey can't. Who forgets how much power their car makes ha ha

Yeah, the one you sold mapped well, Daveys not as much.

Safe limits as in xman said 2.1 bar max and that's what it was running (for example)

I know mate. It drove better too. was planted at silly speeds. This one is a bit wayward. I was telling the lad that bought it I feel like I sold the wrong one!

I'll get this one sorted. Just time and money ha ha
