Hello , does any body know about how many maxmium horse power and torque that a normal engine and gearbox of our vee could sustain? Thanks.

maximum power for engine and gearbox
- Thread starter rickyricky3211
- Start date
1 bhp/ lb ft less than the amount that makes it all explode. 
The gearbox isn't really fit for puspose at standard power levels imo. A few have failed and if all the cars were used like the rest of the clios in the range and not kept for Sunday best then I think the instances of gearbox failure would rise rapidly. My gearbox gave out at a smudge over 40k and it's a club car, so unlikely to have been abused too regularly in the past. The gearbox is from a traffic van (I believe) so that sorts of tells you all you need to know...
Assume by "normal" engine you mean standard. So then I guess the question is how much can the engine withstand before doing pistons, con rods etc.
The answer, from experience of what people have done in the past, is that the engine block is pretty sturdy and engine block durability isn't really the problem when speccing them up. Things like getting rid of the heat (if going for FI) is more of a concern. Having said that if you're gong to the hassle of FI then it'd be crazy not to stregthen the moving parts of the engine.
In terms of absolute numbers it's sort of like plucking a figure from the number tree really, as there are just so many variables. They don't normally run the advertised factory numbers anyway either so you already are starting off on the back foot!

Thanks Taipan [smilie=thanks.gif] My question would be more simple that If my vee install a low pressure turbo, say 0.6bar and expect the engine to have output around 350bhp (with new ecu ). Could this power up-graded still be handled by the our normal engine and normal gearbox?
The engine could probably take it, although there may be certain parts that need upgrading.
Theres no way the standard gearbox could IMO. The standard engine is strong enough to ruin the gearbox, let alone an extra 100+bhp. Would need to find another alternative if you plan using it.
I would recommend you join up as a full member in order to get access to our "special project cars" forum section as you will get to see posts from MikeT on his turbo install.
