Back to the drawing board!

[macka]

I dont disagree on anything for a change maybe soimethings wrong with me hehe

Dr D. The Top secret rom has to go....

When i ran 20 degrees i got 30hp more midrange wow! @12psi

Back to 15deg and i can run more boost but only 8hp more top end but lose driveability mid range!

Adam My turbo specs do match my graph thats ok im happy with that...im not particularly interested in a vertical dyno chart like um.. ps 4500rpm

Rob i guess u have to like a dyno and stick with it so u can monitor inprovements..It is all in all only a tool for development But however what im saying is that i got a minimal increase by doing certain things and went back to the same dyno!

Thanks steve i didnt think so either but wanted some feedback just incase i thought i was greedy..

cheers

Maybe sell it for cash+swap for standard ecu? The top secret rom would be a good upgrade for someone who couldn't afford a s-afc but wanted to get rid of the standard ecu timing problems.

BTW, you're not greedy for wanting more power. It happens, even to the best of us

awesome.. my mates R33 has one also.. never seen another around like it, diff cooler, the lot. :-)

apparently another mate read somewhere that they only made 100 or so of these from the factory.. nice little score!

I guess I should expect this, I've already answered others on the forum. Probably should change my user name.

My R33 GTS-t has a VSPEC diff, yes it does have the fins on the diff like the VSPEC's. That means that I have the benefit of both traction control and Active LSD. It came from the factory with this so I presume there aren't too many of them around.  

The Active LSD is really cool for high speed cornering, causing the back-end to quickly turn in so you can keep the power down.

Your right the Rom is a good upgrade for some people as i did lose power installing the standard one back in for a check, its just a matter of getting another standard unit now...

[Steve]

macka, it just so happens that I have a standard ecu not doing alot at the moment

[macka]

I have a series 1 is yours the same?

Ive heard a S11 is slightly different and not sure if they are interchangeable yet

But that would be great steve what do u want to work out if so?

U can PM me

cheers

[puckish]

Macka are you running the stock turbo? If so I would have thought the thing woulda run outta puff at higher boost levels.

What does the dyno map do above 3500 RPM? Does it skyrocket or mystriously level off at some rev point?

What are the injectors doing (i.e duty cycle?) Fuel pressure? Is the pump suppling enough fuel? Fuel air mixtures may be deceiving. If for example the engine isn't keeping enough fuel in the combustion chamber the exhaust output appears rich.

Just some thoughts ......

[macka]

Thanks for your interest Puckish

Look to the left at my avatar , that snail lives in my car!!

I have a large front mount and 550hp fuel pump

Injectors have a bit of headroom but i havent checked airflow % yet as i forgot...duh!

Gonna try at the drags tonight i have a special pair of slicks now curtesy of GTS-t VSPEC :lol:

Sweeet

[adam 32]

NOTE

special pair of slicks = bald tyres

[Gradenko]

Oh :-|

[puckish]

special pair of slicks = bald tyres

Go Macka...

[adam 32]

with a 12.98 i dont think youll need to go back to the ol drawing board anymore

[JH32]

12.98!

Well done Macka!!

[GTS-t VSPEC]

It was an impressive run Macka, well done. I'm glad those racing slicks I gave you did the job, maybe I can line something better up for you next time. 12.98 will take some catching by the rest of us, but I'm prepared to bide my time until the bigger turbo is on.

Well done again, and nice to actually meet you.

See'ya:burnout:

PS: I'm not too impressd witht the 265's I put on, I still get shitloads of wheel-spin, maybe able to get some Potenza's for the drags, that should provide more grip.

[macka]

Thanks...

how bout them bald Tyres. ey..

That was a freaky time ey...shocked me but she ran beautiful on 1Bar

Maybe the track was prepped better i managed a 2.254 60ft this time..

I thought id teach a V8 torry a lesson but he creamed me with a 12.5 hehe oh well

[Hicks]

You'll need it paul. :lol:

[macka]

Buggered if i could get a 13.8 with only Hick's mods BTW

Good work....

Cheers GTS-t VSPEC looking forward to yours getting built up in the near future!

[Hicks]

Cheers, but im sure it could be better.

But im happy for now, I set out tonight to get a 13 and I got one.:burnout:

[rev210]

Well 12.9 is something to write on that drawing board!
