Mine is somewhere around 300 bhp thats with cams and modified plenham. Throttle bodies would be around the 300 bhp mark too I'm told. ( and they would look awesome )

 

[Tim]

Around 300/320.....what McJames said! Add Nitrous to the mix and possibly anything from 350-400....

 

[Mike T]

100 bhp per litre is a good road setup

 

[k1ano]

As Mike say 100 is reasonably acheivable, I think Honda probably have one of the highest production figures of 120 for their S2000 engine. A combination of engineering, V-tec and high revs. Of course if you start talking about motorbike engines then you can get above 140.

Higher revving engines produce the bigger power figures due to more power strokes but this provides diminishing returns past a point as volumetric efficiency reduces as the revs rise due to less time for cylinder filling at atmospheric pressure.

This excludes racing engines where it is just a question of money i.e. F1 etc. Upto a point anyway - there are physics limitations.

But torque is your main objective though and this tends to come from higher displacement, higher compression, longer stroke or forced induction rather than high revs.

300bhp with standard cams is easy on throttle bodies

what cams do you have James?

I was chatting to a metro 6r4 owner on saturday and he was telling me that the 3.0 lump curently sitting in his rally car (ex Tony pond car) is running 300bhp with one throttle body but thats probably because its a highley tuned engine given 6 throttle bodys and its kicking out over 400 bhp.

It all depends on how much you wanna do to an engine the touring cars with a 2 litre engine have up to 300+ bhp ish . So if you have very deep pockets then big power is possible.

Special ones.

love the way 300 bhp is banded about.... there is nothing easy about it... just bolt this and that on....

simple really.....

Makes you laugh dosn't it.

 

[steveukv6]

Thats the case just buy a cossie or evo - 2 litre turbo. Got back seats then 2!!!!

If you need them that is.

 

[Mike T]

300 isn't to hard - just expensive.

A standard Trophy engine on Motec dyno'd at 294 last week - thats (obviously) twin plenum, slightly higher compression, decent exhaust (still with cats) and Trophy cams, nothing super special.

 

[JJ]

What sort of gains would different cams, free-flowing air filter and a new map give?

James - did you have the head on yours reworked at all?

 

[Tim]

Any Trophy engines with management for sale anywhere? If its cheaper than quoted 4/5K to have a TB conversion (complete set-up) then I'd go for one!

 

[Mike T]

get one from Huger in france

James where did you go to have the work done? Looking to eek a few more ponies out of the mk1 next year if i decide to hang on to her.

A company called GDI.

Why? TB's with correct engine managaement such as OMEX of Motech for those who have £2000 to spend plus larger injectors, and cams and maybe some headwork can easily get 300BHP at the fly from a V6 engine.

The Trophy engines with a twin plenum give 285bhp and that sstil underpowered.

Ask Fred on cliosport and he'll put all your doubts to rest or indeed Andy at GDI who did James' work......James, I believe actually has more than 300BHP with similar mods.

 

[TRW1]

Dynos can be made to show whatever the operator wants them to show.

 

[Tim]

Why so neagative Tim? Is that what happened in your case?

 

[TRW1]

No, not at all Tim.
Just that from experience results can vary widely and it's worth getting more than one opinion, especially from someone who has not sold, or is trying to sell you something.....independant in other words.
There are good and bad operators. I've seen lots of print outs and had mine done several times so you learn a bit about how things work and what to expect from your engine and modifications.
