hi all

just curious to know whether this turbo would run out of puff when going down the 1/4?

and if anyone with this turbo on their RB20 has taken it down the 1/4,

if so, what times did you get?

i wasnt sure if i should put this in the motorsport section either....

thanks

In a VL i know of an RB20DET that has run a 12.9.

With the power they make there is no reason why if you have good tyres and clutch you cant run a 12.9 pretty easily...i think if you persevere and choke everything out of it you can get a 12.5 @ 113-114mph (provided you can get your 60ft time down to around 1.7 seconds)

fair dinkum....

what other mods had that vl got done?

[neil_se]

I ran many 113-115mph runs in my rb20 180sx @ about 1.1bar (stock injectors, cams, AFM, etc).

what times did you get?

I got 12.5 @ 113mph with a 60' of 2.0 that was with a RB25 though.

The VL was nothing crazy, std RB20 with 5 spd and a 2530.

My setup is peakier then what you would expect a well tuned 2530 to be. I was only running 14psi for my 215rwkws when i ran a 12.9 at 113mph with a 2.3 60ft time.

So with 18psi in a 2530 you would expect 220rwkws and more midrange. With a good launch in the 1.8-2.0 sec range you would expect around a 12.5 at 113-114mph

ultimately it is going to come down to how well you can drive as to what time you get. i have a mate with a sigma with a stock sr20 with exhaust and fmic and 15psi boost. he got a 12.56 at 106mph on street tyres, with a 60 foot time of about 1.6). another guy with a sr20 in a gemini got 13.1 at 113mph. if it had been over 1km the gemini would've beaten him, but he got a much better launch.

1.6 60 foot time, thats insane for steet tyres or was that street approved tyres?

[yogi000]

i ran at 13.1 @108mph

making 207rwkw

2530 rb20 ~18psi

60' 2.1 (from memory)

on 12 psi i ran 14.3

on 14psi i ran a 13.9

on 16 psi i ran 13.5

i was learning as i went along that day. i had about 16 passes on that day.
