hummm sounds interesting! good luck alex :) let me know how it goes

ok we are getting some good info now. the thing is every rolling road day i have been on the car has been run in 3rd!!! surrrey rolling road (dyno dynamics machine) triton motorsport (dyno dynamics machine) read performance (sport dyno v3.3)

I was considering this too. But want to get 200 hp at the wheels first without nos. I was considering 25 per bank giving me 300 hp at the fly. Can a non turbo's stock internals handle 300 hp?

that'll be the club foot :yes:

all 6 are clicking. thats what i want to try and do is clear the code 21. once we are back to a code 55 then we can check other problems. btw we did clean the connector.

what i dont understand is that car A has a lower wheel hp then car B but has a higher engine hp then car B surely if the gears were artificially causing an upped power figure surely the wheel hp and fly hp would be consistantly increased too?

im getting welkl confused there loads of conflicting info on here http://forums.nasioc.com/forums/showthread.php?t=1478091&page=2

here is some interesting info i have found.... the reason for the dyno in the 1:1 gear ratio is due to the Dynojet. Dynojet mathematically creates a horsepower number based on mass (which is the known weight of the rollers) and accleration (how fast the car is accelerating the known weight). F=ma From force (F), we can calculate horsepower. Dyno the car in 2nd gear, and acceleration (a) goes way up, causing force (F) to go way up. So by dynoing the car in the gear closest to the 1:1 gear ratio, we eliminate any acceleration advantage or disadvantage caused by the transmission, which gives us unskewed whp numbers (even though Dynojet has a fudge factor in there which makes them skewed anyways and read high). As for other dynos out there (i.e. Mustang and Dyno Dynamics) - they use a load cell to measure roll force (the amount of force the tire is placing on the roller). Based on roll force and the radius arm going to the load cell, we get roll torque. Based on roll torque and roll speed, we can get vehicle horsepower. Vehicle horsepower and vehicle RPM gives vehicle torque. It doesn't matter what gear you run in on load cell style dynos as they are measuring force, not acceleration. Force does not change from gear to gear.

ok so say both cars are MANUAL Z32 car A.... was run in 4th gear (1:1) 189 hp at the wheels and calculated back to 243 at the fly 210 ft lbs of torque car B..... was run in 3rd gear 193 hp at the wheels and calculated back to 240 hp at the fly 217 ft lbs of torque

but does it actually matter? as the dyno calculate the fly hp via the rundown after the load? a lot of the cars on here being manuals are run in 3rd? my z was run in 3rd on the rr days i have been on and it seems common across the range on dyno days. so assume it dont matter as the dyno is cleverer then we think

what is the correct gear for a power run on a dyno please. now i thought it supposed to be 4 as thats the closest 1:1 ratio but most of the sheets state 3rd gear run. now with modern dynos i assume it doesnt matter as it calculate the loss through the drivetrain on the deceleration stage? im sooooo confused as i have been comparing dyno printouts on some cars and there are some interesting findings

caz and i had a look round a couple of these when we were looking for a bed in the sales. they are cool but waaay overpriced. we settled for this instead LOL

tested for spark on all connectors flooding wouldnt cause a code 21 tho would it. there is still a problem on the ignition circuit regardless weather its flooded or not. but we will try taking plugs out. also going to try a continuity test on the loom from ptu to ecu.

another update. tried another ecu on the car today. also came up with the code 21!!!! FFS!! its sooo annoying as she wants to fire i can feel it in me bones LOL EVERY NOW AND AGAIN SHE STUTTERS THEN JUST CONTINUES TO TURN OVER what pins can i check on the ecu loom to check continuity to the ptu? also when we tried the cas the injectors clicked. now could there still be a potential problem there?

i had this too only took 1 day to go across 4 states of america and to the uk .then spent 2 days at customs in the uk!!! dont panic mate , it will turn up ;)

oh shit!! perhaps it might be something to do with me redirecting it to me for my na to tt conversion. cos you keeep posting up goodies on a wednesday when im out LMAO!!!!:tongue:

currently kicking around in a 1997 facelift mk1 clio 1.2 biarritz. as you can probably imagine the fuel saving is emense but the smiles per mile is dia!

its cos your getting old and lazy:tongue_smilie::tt2::tongue:

excellent news. cool taking her for a spin without the bonnet too.

welcome back mr pete :)

alright phil welcome aboard. ;) nice friendly bunch on here mate . gaz

does this look right to you?? the other way round it seems they strain the pipe when bent back on itself??

so its the abflug type 3 bumper

me wrong hahahahaha doh!

pentroof i think
