Top RB20 Club... do you have over 260rwkw?

[silver gts-t]

yep, fcon all the way..

didn't bother with navigator

[Roy]

Was that on the BD4s dyno...my understanding is their brand of dyno read less then Dyno Dynamics so thats a great result.

But more then anyting, i want to know if your happy with how it drives on the street. You think it is too laggy or a nice compromise between mid to top and acceptable city driving????

[silver gts-t]

yeh on BD4's dyno

its laggy. but it dosnt really bother me much..

full boost at 4500rpm.

i think if more time was put in adjusting the ebc i could have better low range but im out of $$ for the moment, lol

good to compare graphs at 20 psi once you get them up ...

my run went from 22 but tapered down to 20 psi

have to get some of these hi po rb20s running down the quarter mile

Diff goes in this weekend, then hopefully next Friday night at Calder im going to give my car another run at 1.5bar...hoping i can get the 60ft down to 2.0 flat and pick the mph up from 113 to about 115-116.

Im hoping for about a 12.2-12.4 , but will be stoked with a 12.6 and no breakages. Actually i will be happy with a few runs in the high 12s with no breakages:)

My problem is having been playing with cars so much of late im behind with work and some courses so no spare time

I did some standign 1/2 mile stuff at an airport lat weekend, and with only 1bar up the old girl she placed 18th out of 95 odd cars, full or Turbo Porches, GT3s, GTRs, Ferraris. I was only 8 tenths slower then a Z-Tune

What type of dyno do BD4's use?

its amazing how much a good boost controller can effect spool, when we were tuning my car started off doing a run with the controller off and it made 12psi at 4300rpm, took a good 800rpm for boost to go from 3psi to 12psi... then we switched on the controller, did the relearn and it now gets 14psi at 4000, just shoots straight up. averaged a gain of about 40hp from 3k to 4.5k! and thats just a crappy old HKS evc 3.

If only SA had a running drag strip, who knows wtf bob jane is doing down here...

Not is. "Was". Isnt there dramas with certain drums full of nasties that may or may not have been used for land fill?

[kwazza11]

To be honest that wouldnt surprise me in the least, last i heard they were resurfacing it (for the last 8 months). they've probably stumbled into something..

[Cubes]

Apparently the City Dismantlers bloke went to purchase AIR then Bob Allrounder found out and pulled the pin (bad blood between the two). There was a little thread in SA regarding the speculation of what was going on. Apparently the city dismantlers dude is switching the direction of which the drag strip runs.. So your not running in to the sun as the afternoon approaches.

true.. im going to fiddle with the EBC.. if i can see any improvement ill get it back on a dyno

[kwazza11]

thats something they should of done a long time ago. would be even better if they could lengthen the run off to allow the fuelers etc to come back but seeing as there is roads either end of the track it doesnt seem likely.

[legend01]

Whooo silv

Ya getting it up there im gonna havta watch my time's you"ll probably knock me out my spot in the times section.

Gonna havta hurry up and get the new car finished .Compition its fun hey ,good luck :-)

cheers Peter

My apprentice ran 13.9 @ 98 in his R32 4 door. Stock standard running 13 psi boost. was 1.85 sixty footing on MT street radials. I wanted too see what it would do standard before it has nitrous fitted, new fuel pump & clutch. Might crack a 12 sec pass.

[japwpn]

heres a dyno sheet im so stoked

Is the rpm scale correct? What is it like to drive? Is it right that its about 180rwkws at 5,100rpm?

Is there any chance of getting the boost into it sooner?

[japwpn]

its not to bad to drive the rpm scale is correct

as for getting it onto boost sooner to be honest i was expecting boost much later than what its coming on at these turbos are rec for rb25 and from what ive seen they are getting them on at 5000 rpm there abouts so u would think that mine would come on much later i was very surprised
