Nissan 200SX Club - South Africa

well done PFB

Not bad at all.

Ha!, no wonder you can smack those GTIs and STs...

I'm just sooooo glad you didnt paint the valvecover blue...

Also, the lumina ran a 15.7ish on friday too, might have been a 15.9... That is all...

Eish Sokar....that's harsh

And your lumina did what?

Thanks Guys, I was impressed myself

Because I couldn’t get on a dyno before the install I took the Sentra for a spin around the block on the morning logging data and the AFR’s, After the install I Did the same thing keeping the redline at 7300Rpm just for the data run.

After the install on start-up the car at idle the motor was consuming more air, I could see this on both the TP value and the MAF voltage returned, Taking the car around the block, I had to richen up and extend the TP value of the map (Basically the pulse width at 7000Rpm when compared to my old data log , I had to add 11% more fuel to keep my 13.2 AFR, I had on the old cams.

I settled on a +4\-4 Cam timing after trying 0\0 and +2\-2, When logging data on those settings the MAF and TP wouldn’t match the values received on +4\-4. I know the testing isn’t as accurate as a dyno but it defiantly showed results when logging.

I played around with he cam switch points , I eventually settled for 5100Rpm switch on both cams


Impressions

This is where things get interesting to me the car feels slower but the nistune system offer like a stop watch system based on RPM and I can see the car is quicker on the system plus, I can see the car is consuming more air but one thing, I can say is the car is allot louder especially in lift. I’m now really considering going with a 76mm exhaust system for the car.

On a Side note, I also drove my SX around yesterday and all I can say is if the SX’s got a good pull away it would cream my sentra. Driving the SX is like driving a roller coaster it breaks traction mid first gear and the only way you get it back is by stepping off the pedal and will easily break with a snap shift from 1st to 2nd and its out of tune and hasn’t been serviced in 4 months.

Anyway thanks guys

Nice work Ashley!! always admire your work.

Nice cams, should be interesting to see what she does on a dyno.

As promised here are pictures.

I was there on friday with the new set-up but only ran a 15.5 again

I did two runs (15.5 and 15.6)and both with allot of wheel spin, I just want to do a 14.9 and I will be happy.

if you had traction before the upgrades then normally after a power upgrade you have even less, so ye, you won't really go faster, exit speed might be higher though
