Got my car on the dyno today at the scooby clinic in chesterfield.

after using blocks of wood to drive it up onto the dyno we where away.

 

Spec before 1st dyno:-

 

95 j spec tt auto

 

hks coil overs allround

18 inch alloys 265,35,18 rears 245,40,18 front

veilside body kit

bomex front bumper

hks cams

hks intercooler

hks dump valve

hks fcd

greddy profec b (switched off for this run)

boosting at 1 bar

2nd decat

1st cat still in place

full 4 inch hks cat back race system

normal ngk plugs (didn't change them for this run)

uk turbos

full hks engine rebuild with studded head and hks gaskets all round

hks injectors

standard denso fuel pump

oil temp gauge

water temp gauge

oil pressure gauge

boost gauge

hks flowmaster induction kit

modified viscuss fan

silcone hoses allround

silcone radiator hoses

el glow dials

uk headlights

front tein strutt brace

 

dyno was running with profec b switched off running 0.9 tp 1.0 bar boost

 

352 bhp at the flywheel

292 bhp at the rear wheels

 

andy at the scooby clinic said it was running a tadge lean. he said that was more than likley down to the denso standard fuel pump. (i didn't have time to install it!)

 

 

Spec for next week.

 

same as above with the following mods:-

 

PROFEC B running at 1.2 bar (tuned on dyno)

walbro fuel pump installed

ngk uridium plugs

1st decat pipe installed

pull the trac fuse

 

andy said that the cams will come into their own at 1.2 bar and he reckons with the above mods next week he should be expecting 400 bhp+ at the flywheel.

 

 

i will post the results here next week!

 

 

regards

A very realistic result :D

 

It might be worth investing in an AFR and/or EGT gauge as she appears to be a little on the lean side during 2nd turbo spool and for the next 2krpm

 

i asked the same question. andy thinks that the walbro pump will solve that. he said it could even be the sparks that are a bit shitty and the new ngk's might make the difference.

 

thanks homer

:cool:

Nice :thumbs:

 

Was Pat there as well?

 

what does he look like? there was a guy called kev, he owns it i think. nice bunch of guys. they are very helpfull and they seem to know their stuff. kevs scooby 22b has been running 500bhp for the last 20k miles.

 

a big word of caution, if you have a low car like me, make sure you drive very slowly going up to the farm. the road is crap and you can easy take your front spoiler off. it's ok if you takr your time.

i thought that 50 quid was spot on for dyno. they said 75 quid when i take it back next week for boost controller setup.

 

can't complain at that!

Pat can normally be found working around the dyno area but he isnt there all the time, big fella that does most of the mapping :)

 

Yeah the road is interesting, I honestly thought I had taken a wrong turn on the way there.

Nice results chap

 

But get those AFR's double checked as it is very lean! That lean with the first cat in place will be producing some extreme exhaust gas heat.

 

I mapped a similar spec'd car and had to keep the AFR around 11.2:1 with the 1st cat in place just to keep the EGT's to a safe limit.

Boost controllers normally are better setup on the road as the dyno doesnt always give accurate road loading, they sometimes over boost on the road after.

 

whats the difference between gain and set gain on the pro fec b. one is measured as a percentage and the other measured as in bar pressure. also there is start time for spool up speed. i'm sure its easy once i get ithe hang of it, but the instructions are w@nk.
