And that's day one of mapping!  lovvveeee the car so much more now.. drives much nicer.

here is a before and after.. Gtech numbers, for those that dont know this is done on an actual road run, and therefore is Wheel horsepower minus wind resistance etc (about 10hp typicaly).

The before is as the car was with a standard HASS kit (black lines)
After (red lines) is the new setup running the same boost as before, Next step setup boost controller   s:bounce: :bounce: s:bounce:    s:bounce: :bounce: s:bounce:  
The rpm needs recalibrating a bit, but i wanted to use the same settings as I used to measure the car standard, clearly the rev limit isnt at 6000rpm but the gtech picks up rpm through the power supply and needs calibrating to be accurate.



So about 210hp wheels 250hp crank on 8psi.. which is quite random as i insured the car for 250hp as i wasnt sure what it would make lol. so gonna need to up the policy after i play with the boost.

Is 250 about right for 8psi? what does that kinda boost normally make?  need to iron the fueling out a little more, but dont think it will change peak power much.

Map looks smooth and I would be happy with this numbers, it's a different animal I'm sure
Another one won't hurt  .....

Nice looking graph, looks like the power delivery is quite smooth?

stupink

#53
Yeah its ridiculously smooth..  even the previous setup on the graph felt pretty smooth, the G meters are so accurate that they pick up things you can't feel. who says turbo's have too much surge to be driveable  s:mrgreen: :mrgreen: s:mrgreen:  

only problem I have at the moment with it, is it pulls harder and harder then hits the rev limit.. so im going to have to get used to changing gear by rpm rather than waiting for the power to tail off a little like you typically do.

Haha. Very much so.  Insurance goes up quite a bit at over 250hp. So I'm now pondering solving two problems with o e stone. Up the boost but at 250hp cut it back and hold at 250. Insurance company happy. Car faster so I'm happy. And means it will tail off again making gear changes easier.
I'll have to see what happens.

what turbo are you using? good to see you are in Devon, i live near okehampton but work in plymouth, recently bought a MK3 to play with and will most likely turbo mine in the winter so great to read your build thread for inspiration

How could they know in the event of an accident what psi you're running and what hp it's putting out?

Not condoning it, just wondering myself!

I was thinking the same. Bhp figures are very subjective.

and another factor, in the event of a complete write off.. I hardly imagine they're going to stick it on a dyno?   s:crazyeyes: :crazyeyes: s:crazyeyes:

Its a Gt28R, i don't believe you need anything larger on these engines unless you start rebuilding the block for high boost, but i'd not like to run anything smaller on a naturally aspirated engine thats not been de-compressed.

I'm sure a lot of people do tell porkies, and get away with it fine..

*IF* you cause a death by dangerous driving or put someone in hospital and the bills are gonna be astronomical then you'd be suprised what insurance companies will do to avoid having to pay out.. their easiest tool is the internet, its no coincidence they give you a discount for being a member of a club (where you blabber about how much power your car has lol)

but yeah it would indeed be quite a bit more effort than they'd probably bother with for small claims. I know these are older cars, but you'd even be surprised what a modern car ECU logs and dobs you in on to the dealers diagnostic computers etc.

I'm an ADI, needless to day, i'll insure it as it is, but that doesnt mean you can't play the system and tune the car to a good insurance deal  s:D :D s:D

I see. That's mad, wonder what the mk2's ecu logs. Still, time and a place for everything, can't afford to drive dangerously!

Sensible, fair play

Had trouble getting my Emanage to control the boost, but its sussed out now. more to come, just a minor play today to get it working.

Previous results.. 250hp, current results...  250.. haha..   Same insurance, faster car  s:D :D s:D  win win.

black is the previous results in the last graph i poste (which were red)..   red is how it is now, mostly stopped boost creep by using the Emanage to hold the pressure away from the actuator until the required boost is reached to stop it opening early, the car is now running....... 8psi still. lol. just the whole range not just up high.  so next step maybe 10psi dropping to 8psi to keep the power down.  thats probably where i'll leave it then.



Some figures for the geeks (sadly with a lot of scrabbling about on my crappy tyres and dusty test site, but at least that means its quicker in reality not slower)

0-60mph 5.0s on the dot.
0-30mph 1.9s
30-50mph 1.7s
40-60mph 1.5s

5.0 to 60 is pretty impressive ! Power curve looks sweet too

New Shocks and springs and EBC brakes and hells brakelines now fitted, new fluid flushed...

pro-race 1.2 purchased and currently attacking them in my shed with my homemade sandblast cabinet ready to paint and get some decent tyres.  #alloypaintisthedevilswork

Silly annoying tapping noise still there, no better no worse...  But i've picked up another engine (a smoker) to strip and rebuild ready to swap over if it does break in a rod-tastic block destroying manner.

Like your thinking about rebuilding the engine, it's def on my list of things to do. Can't be THAT hard can it?  s;) ;) s;)

stupink

#67
Didn't really do many pics this time. was a ballache paint stripping the plasticote.. but a mix of paint stripper sandblast and mechanical removal.

the rims were corroded and lightly curbed, was going to re-do them black,, then kinda didnt..

after paint strip attempt 2093 before final sandblasting


Then painty prime prime, spray spray.



All dry ready to go on, may have oversprayed my entire garage red lol..


New shoes.. not sure why they keep looking orange, they're mostly red (hammerite smooth)

Think they'd look better on my car, when shall i come get them?  s;) ;) s;)
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

Wheels look good!

Are they 15's or 16's?

Width and offset?

Brave choice but you have the bhp to pull the look off!

stupink

They are team dynamic 1.2. 16" 7inch 35offset I believe.
Currently on 195/215 nankang/Goodyear (goods at the rear so don't think mixing an issue). But yoko ad08r going on 205/225 soon as I have the pennies.   Sits a little lower than the PIC as its off road on uneven ground. But perfect height. Can still get full lift jack under front and rear beam jacking points. ☺

Not totally happy with the handling yet. I'm thinking maybe an uprated front rollbar may be needed.
