Car won't take timing with out knock
Dose Pipe Sutututu replied to MatthewT85's topic in Engines & Forced Induction
To rule out a cas issue.. load up the car say at 4k rpm on the dyno and make sure all the cells around that are the same and using a timing gun to see if the timing is synced. Easiest way to rule out if the cas is playing silly buggers -
R33 Rb25det not performing
Dose Pipe Sutututu replied to BrokenR33RB's topic in Engines & Forced Induction
Run less boost, stock timing map and fuel maps were not mapped for boost.. Have a feeling running 0.7bar would feel better -
do you have access to a wideband? see what's going on with the o2 during o2 feedback enabled and disabled.

which injectors for E85
Dose Pipe Sutututu replied to MrSquigle's topic in Engines & Forced Induction
ID1700 stainless, not modified on a lathe like other brands. -
not really performance related but a tyre review nevertheless Tyre: Hankook Ventus S1 Noble^2 Size: 205/50/17 Car: Mazda 3 SP25 BL Comparison Tyre on Same Car: Bridgestone RE002 Quietness: 8/10 - day night difference in terms of noise compared to the RE002 Acceleration Grip Performance: 7/10 - decent grip, mash throttle with VSC off very little spin, nearly no spin, RE002 (old) would fry and make smoke Lateral Grip: 6/10 - not as good as the RE002, feels the side walls are much softer - however need to remember these are commuter tyres. Value: 8/10 - at $145 per corner installed, it's pretty good (yes I know right now you can get RE003 for $195 each - not fitted and 3 for 4 deal) Overall, decent quiet tyre for daily use. Appears to be decent with grip, although they're brand new.. give it a few months and I'll give an update.

Project Snoopy
Dose Pipe Sutututu replied to Coullsy's topic in Members Cars, Project Overhauls & Restorations
ground off the fuel if you haven't done that.. i.e. that bypasses the drop resistor which will lead to premature pump death -
Sell 34R for something Euro?
Dose Pipe Sutututu replied to No Crust Racing's topic in General Automotive Discussion
SQ5 would be my pick -
Shoota's R33 GT-R RB30/26
Dose Pipe Sutututu replied to Shoota_77's topic in Members Cars, Project Overhauls & Restorations
ahhh gotcha, well I have a solution for that problem.. go single LOL just kidding -
sounds good Goals for 2017, sell car, buy bigger house so can do car mods, buy Supra RZ (yep going to the dark side)

mount it before the cat pointing toward the gearbox -

drag rear set ups
Dose Pipe Sutututu replied to Adz2332's topic in Suspension, braking, tyres and drivetrain
wallah you need: traction rods, extend them about 10mm - this will reduce the toe out ramp and camber ramp camber rods, run about -0.5 degree or even 0 - because drag car delete the entire HICAS rubbish, i.e. get a proper HICAS eliminator that deletes the ball joints for the hicas system get a proper mechanical diff, the VLSD is aids no matter how much is "locks" it's all smoke and mirrors subframe lock collars diff bushes Then alignment: Toe in about 2mm each side, Nissans naturally toe out on squat not too much camber don't lower the car too much you don't want the control arms pointing upwards I have about 370kW+ at the rears and I barely light up 2nd once the tyres are warm... albeit these are NT01, with the NT05 2nd gets a little silly. -
Bc Racing Coilovers?
Dose Pipe Sutututu replied to RB25PWR's topic in Suspension, braking, tyres and drivetrain
My exact thoughts - pretty sure I said something similar before and someone had a sads. -
since there isn't much interest.. I will part the car EOM March 2017, after I drive it gentle around Wakefield Park.

Here's another photo of the car never driven hard... it has never been driven in the rain or raced. (the track looks wet and it looks like a rainy day.. but it's the internet, anything is possible)

you want to work out power, drag strip. x weight can going so y speed in z time and k distance (factor in some basic air drag) - that is much more accurate then working out how much power a motor makes based on air flow and fuel usage. You need to remember a motor is not 100% efficient, and x air/fuel does not equate to a direct 100% energy transfer to mechanical energy - there are losses such as heat due to inefficiencies.

yes rough rule for approximating the size of injector you need.. but the OP wants to determine how much power his car is making based on injector DC.. that's obsurd.. just as obsurd as a moron on a Facebook page telling someone to install a resistor pack on their high impednace injectors because their car won't crank over.
