Right guys .. This is doing my head in . I've been doing quite a bit of research lately on zed performance parts and projects as i want idea's of what is best and isn't for my build.

 

In almost every forum i've been registered on i keep/kept on hearing about how the americans exagerate on their bhp numbers and so many people critize them in the u.k that i started to believe we in the U.k were right.

 

However after searching i noticed that in the u.k theres barely any parts for the zed lets say .. U.k made? Regarding turbos,injectors,manifolds, ECU managements etc ... mostly comes from the americans and the only ' big' thing that i know of is the Emerald system. Yet people still critize them ? Seems to me that if it wasnt for them we'd be completely lost in terms of ways to get these products.

 

As for the bhp numbers , i never quite understood 100 percent why people say they are rubbish ? i've read so many times the words ' whats your horsepower? and please dont say yank rubbish bhp ', i mean i've read in some places that its because the dynos are different or something , but the thing is even though it seems they have these large numbers like 900+ all the time , they do have the quarter miles that prove it ?

 

I saw that specialty z made 499 RWHP with stock turbos ? of course with alot of supporting mods but why do we say the max is more or less 400 at the fly?

 

I used to always critize them too tbh lol from reading so much stuff on the internet etc but this is really starting to confuse me now , im yet to understand why we're right and they're wrong.

 

And btw im not american guys,so please dont hate on me LOL . Just thought this would be a good thread maybe : )

I think you jut have to take their peak bhp readings with a pinch of salt as they usually use race gas to achieve them. Personally I reckon they are quite reasonable if we were to do the same.

The figures quoted for the max BHP on stock components are intended for everyday driving, rather than a put it on the dyno and see what the highest number we can get is.

 

I mean the 499RWHP was probably running race fuel and running at 100% max on it's tubs. If we were to set up our cars for max BHP with race fuel rather than our everyday driving and 98 ron. I think our figures would also be significantly higher.

 

In terms of difference between UK and US dyno's - none that I know of. Difference in terms of BHP - none, it's all worked out the same. Difference in the way we prepare the car before the dyno - This is where the difference is.

Ah alright , i completely forgot that they use race fuel ,we only use 98 ron here . Never knew they set up the cars differently though, thanks guys . Understanding it better now .

 

Is race fuel even available in the u.k ? i mean of course buying it on a site/company , just out of curiosity.

If you do a forum search mate, this topic has been debated many times on here. :cool3:
