any1 else up there

Can't make that meet Sam, but I wanted to say thats a great time your running

shame. thanks would lov to get it in the 12's tring a little more nitorus this time

I might just pop over and use the pod as a place to run my new build in without annoying my neighbours

got my car running sweet on the nitrous as i found out while it used to misfire on anything above a 75hp shot. i was running it to rich to be on the safe side, so decided to go back to basics n carry out some static tests got a good ratio. at the end of sunday i was running a 100hp shot with no misfire or spluttering. and was getting some good results

my previous best was 13.37@110

i beat that a thew times up there over the weekend. these are the times that i got in order that i bet my previous best.

on 85hp nitrous shot i got
13.36@111
13.35@110

then on the 100hp shot i got
13.22@111

then on my very last run i got a great start but misfire rite befor the finish again and my alternator belt came off some how which i was lucky as i dont run cam belt covers n could of went it there and damaged the engine lol, but run my best time of

13.17@109

very pleased with result but would of loved a 12 second run. i am detemend to get a 12 sec run on standard internals n box

Videos n pics to follow soon.

Excellent results Sam. I can only dream of that.
Do you happen to know what the AFR`s are on your 100 bhp shot run? And what jets do you use on that shot?

Paul.

dont know the AFR but the jets i finaly used and went the leanest where

nitrous 200, fuel 60. with 2 degree retard ign

to me then jets seem very learn but on the static tests i used a 70 and 20 and reved to 5k so still not red line. and the 200 and 60 is just slight richer than the 70 n 20 it did on the static.

Wow, you got some balls to try a N200/F60 jetting. That`s a 3.33:1 ratio.
I did a N200/F80 jetting last year on the stock ecu and my wideband averaged a 11.3-11.8:1 AFR from 4000-8200 rpm on the 1/4 mile.

I`ve got Hondata flashpro management now. Although it doesn`t have nitrous control yet, I can optimize the afr, igntion, cam angles etc, to get a better grip on the nitrous mixture. I might try a N200/F70 to see how that will work.
That is if I can find some nitrous here in Holland.
