Rolling road results

First post!

Hi all,

Just had my car on the rollers to check power. Making 180 hp at one bar boost,

any advice on the graph print out would be much appreciated as don't really know what I'm looking at!???:coffee: Want to get it to around 200, trying to get fueling sorted:scratch:

(dotted line is a run with 1.5 main jet, 27mm venturi, 0.9 air corrector, standard other jets. Solid lines is a run with 1.4 main jet, 27mm venturi, 0.9 air corrector and 2nd stage drilled to 1.2mm)
The rolling road guy couldn't advise
Heeeeelp

Am I reading this wrong?
(I'm colour blind so bear with me:rolleyes:)

It looks like you have got one massive turbo on there, or the venturi is too big or something:confused: You're not on full boost until 4500:confused: and something taking that long to get upto speed should easily make 200bhp. That said, 1bar aint pushing things.

My advice?

Stick to the standard venturi and start again.

BTW, What turbo are you useing???

[old skool turbo power]

With you having a ebs there i wouldnt worry about the power and id just enjoy the std boost:laugh:its still not bad imo:scared:with it being a standard as well it would be even better :cool:a rare car there mate:agree:

Hey old skool turbo power, yeah gettin very rare now! Was a rusty heap when i got it and hardly nothing original left on it:sad2: different seats, carpet, lowered, big wheels exhaust etc etc so I thought what the hell leave it as it is and sort the engine for a bit more fun want to try an get original interior back in and maybe original colour back on as it needs a tidy again on bodywork:crap:
