Hey Darren, what is the torque numer on the graph actually repesenting? Is that the torque at the rollershaft? I ask because without the RPM of the engine being logged the torque of the engine can't actually be calculated. This is a graph from Wests dyno where the RPM trace was hooked up. The number is still 'funny' though as due to converter slip there is a torque multiplication effect happening, SERIOUSLY inflating the number. When you've dynoed yours Darren, what percentage slip have you seen with the converter? If you havent actually measured it, if you've got a dyno sheet, diff ratio # and tyre dia. I can calc. I'm interested as I'm trying to work out if the converter slip I'm seeing on the dyno is normal or not. Also, have you guys had any experience tuning with NOS? Hey, SKY30, you got that boost control hooked up yet? Sorry I haven't got back to you-work has been a touch busy of late.... Some original photos have not been recovered yet.

now ur talkn... u guys know ur stuff hey... love reading this **** and learning

what do you want to know about the gas? I just hooked up my direct port foggers and might get it tuned in a week or so, going for a 100 hp shot (pretty much smallest ones i can get) going to have to probably knock 3-5 deg of timing off to compensate for the large increase of cylinder pressures at lower rpm (start injecting at just over 4000 some where and get the computer to cut it 300 rpm before limiter) dont run it to limiter or there will be some big bangs. As a rule i have seen generally 1 deg reduction for every 25 hp of gas. With out a pressure guage and bottle warmer its almost useless, you want to tune it at around 950ish psi, sometimes you will connect the bottle (full) and see 700 psi so you must heat it to the same temp it was tuned at to get repetable results (obviostly). Bottle Temp Bottle Pressure (deg. Celsius) (PSI) -34 167 -29 203 -23 240 -18 283 -12 335 -6 387 0 460 4 520 10 590 15 675 21 760 27 865 36 1069 Not sure if thats what you wanted to know/or what i said was too basic. HTH

[quote=SR910]Im not overly bothered, I only seen this thread because my friend told me about it, and the argument of hitech reading high is still going on, which in my opinion is a load of ****. you able to tell me who has actually said that hi-tech's dyno gives high readings?

well said gav... haha

ok, lets leave it at that. I'm not fussed who tunes my car, providing its safe, continues to return 10.6/100km's cruising around with the odd squirt and feels good to drive. Thats all the matters. For my needs... I wouldn't ever bother with an autotronic/motec, simply overkill. The PFC runs sequential injection, 6 coil drivers, knock sensor and o2 sensor utilization, cold/warm starts and drives like factory, awesome interpolation and awesome large injector control. There's no ecu that comes close to it when you consider the 'basic' features you need and that it can be picked up for under 1k new including hand controller. Its the ecu of choice for the japs limping their 1200hp RB's around the streets. Some original photos have not been recovered yet.

My mate has shown me how this can happen when using the wrong ramp rate on his dyno.

dont know, i havent seen that before, but i have used rr from 100 to 150 with the same results. the only problem that could happen if you let the rollers spin to easily the car might not come on full boost (extreme example) and not make full power.

The only reason i did is coz ur a smartarse!! Wat flattering rwkw runs u seen frm shauns????

who u talkin too alex?

U mate

so u dont actually believe that hi-tech's dyno reads higher? so u were just saying that to give me sh1t? ...... i think that would make u the smart@ss mate.

nah im just wondering were u get ur facts from that shauns is higher?? so far theres been no proof of that on here...... and personally i dnt give 2 ****s ill let the track talk

if u dont care then why did u post? but i agree with u, dyno figures arnt the be all and end all, and i never said that they were. i posted not because i care so much for dyno figures, but because someone said or incinuated that hi-tech's dyno reads high, higher than boostworx, and that boostworx has a harsh dyno. from what ive seen, i think that's bul1****. as i privately discussed with another member on this forum, we didnt think it was a good idea to go bringing ppl's cars into the topic of discussion and we agreed to leave it at that. but i agree with u, let the track do the talking, i know ppl that rave on about their dyno figures and say that "this will run this" and "this will run that" down the quarter. but at the end of the day, ur right, the track does the talking, and it already has.

mate the track hasnt said much at all yet....

really.... didn't see the 10.5 adam ran back in august?

Yeah Ive heard about that Calais, havnt seen it much since though? lol
