Due to the majority of our cars being around 17 years old plus, how would this affect our bhp.

 

I remember seeing a series on top gear where they had to get an italian supercar and then put it on the rollers. There was one car that lost around 110bhp in 20 years if my remember correctly.

 

Is there a rule of thumb out there to go by. A friend suggested 5bhp per year but i thought that was rubbish as that would knock 85bhp off if the car was 17.

Well i cannot say from my car as when i got it on the rollers i had upped the boost etc....

 

However one that has always amazed and impressed me is 300zx_girl's zed. As far as i know, it is standard with the exception of a stainless exhaust and she made 283 BHP!!! And her's is a H-Reg so roughly 18 years old now!! :bow: :bow:

 

I think a massive proportion of the outcome is to do with just how healthy and well maintained your engine is.

 

Only one way to find out really, get yours on the rollers if its standard and find out :D

I think this will depend entirely on how the car in question has been driven and maintained over time. Bad maintainance and thrashing the nads off it doing 20k miles a year will cause the engine parts to wear faster and hence lose efficiency faster than something well maintained and driven 'sedately' 2k miles a year.

 

And remember, some of the cars on this site have double the BHP they started out with! :D

There is no hard and fast rule. It depends on so many factors, how the car has been maintained/stored/driven/mileage.

That can't be right.

Mine has doubled in power over the last 18 years :confused:

 

:D

:rofl:

 

It's a good vintage!

Thanks for the advice.

 

Well thats good news, only just bought the car off my brother a couple of months ago, was serviced regularly and only has 51k on the clock so hoping not alot of the horsies have got away. My brother drove it like Miss Daisy too for 4 and a half years. Suppose the only real way of finding out is by going on the rollers.

Also petes zx got over the std hp with just an exhaust :cool:

I remember that Top gear episode.

The difference there being that they were firstly far more than 20 years old and secondly they were 3 ITALIAN supercars in very poor condition.

A Japanese car in the 90's would have been built to much finer tolerances by robots and technicians not hand built in a shed in the 70's!

 

For what its worth my was rolling road tested at close to 340 fwbhp (1mm boost jets fitted+Zworld chip).

Topgear

 

Remember the new injector test ?

gained about 50bhp by putting in new, forgot what car it was now, but one hell of a difference...

It was the renault thing to try and make it go around the track as fast as an evo

as far as i'm aware, a car which has been maintained shouldn't lose any power at all.. and an older/broken in engine will respond better to modifications. But I remember that episode of Top Gear too, and they did happen to use 3 ITALIAN Supercars, and Italian reliability is as good as.... However, I do recall another episode of Top Gear where they bought used cars for under 2k? and the verdict was.. if your going to buy used.. Buy Japanese...

I've also seen top gear test the same models of cars but one a couple of years older with a lot of miles on the clock and properly run in and they leave the new one behind.

Mines on 113k miles, rolling roaded around 108k and managed to reach 324bhp with EBC, JWT chip, and full stainless........

What boost?

What boost?

 

It was on ''hi boost'' setting on the RR and doesnt say on the printout, hopefully not too much! I think its back to standard now, i did post a thread asking how to put it back to standard but no luck

You need to find out what 'hi boost' is set to. If it's 14PSi, that's not the greatest bhp figure in the world.

To be honest i like power, but i wouldnt want to damage it really. 14psi is standard isnt it? When i last drove it, i dont remember the standard boost gauge going any further over 12-14psi, but then again, it wasnt on ''hi boost'' lol, i dare put it on hi boost!

7psi is standard

No it isn't, stock boost is 9PSi

No it isn't, stock boost is 9PSi

 

Oooooooo! So mine isnt running wickedy bo hi boost now then! Its running just over, at the most, 14psi i think

7psi is standard

 

That's safety boost

Depends what your hi-boost is set to mate, that's why you need to find out.

Yeh ill have to have a look, i just read that the figure was 324.8 on hi boost, and just under 300 on low boost, is that good for an engine of this milage do you think?

These are also fly figures no wheels

How did they test it with no wheels? :rofl:

 

Doesn't really mean anything if you don't know what the boost pressure was.

Need a decent boost gauge on it to see what you're getting on high or low, the standard gauge is pretty useless.
