Was in Woolies readin the latest Motor mag and they had a review of the aformentioned cars. Of course the first thing I flip to is the performance data. What stunned me most is these cars are pulling 109/110mph traps? How can that be possible? You need ~200rwkw in an S15 or a tad more in a R33 to do so. And these cars have substantially less power and more weight. The power to weight ratios are no better than a stock R33/S15.

Anyone smell BS?

are you saure they are saying that they are hitting that speed buy the end of the 1/4 mile, or do they just have the times it takes for them to hit those speeds. as any info i can find on the xr5t says it takes over 16 seconds to hit 100mph, which would put it well past 400m.

i have a quite a few motor mags and they don't usually do 1/4 mile runs at the drag strips. they usually bolt a big thing to the side of the car that has a wheel that runs on the ground.

most of the tests i have seen (infact all of them) have the times it takes for the car to get up to about 160-170kmh, even though they might do the 1/4 at 155kmh.

but either way i'm going to go to the newsagent tomorrow and check it out.

Shit !, read about the MAZDA 3 MPS and watch the fifth gear review on it....thats things got a SHiT Load of tourqe....too much i will say.....my stock r33 will be blown to bits if that 390NM got stuck in to me....

xr5 has tad over 300nm of torque from 1800rpm onwards, as a result the 6 speed has tripple synchros first 2nd and 3rd gear, plus a proportioning valve in the hydro clutch (clutch in you cant rev dump) :P. nifty lil car, ive driven them, not to sure bout the holden however.

i work for ford, and have had a xr5 in and been in one when being driven, nothing compared to my r33 gtst with 205rwkw :P even on 7psi my skyline feels faster. These cars do hit high speeds, but no way are they 13 second cars... No way in hell. If the GT-P is a 14.0 second car or thereabouts and the typhoon is 13s or so, the xr5 is nowhere near as fast as either of these cars.

i dont have 205rwkw..would't mind though.......but bugger....scary thing is my GF likes that car and she likes the Mazda.....

so all of these are FWD right....do there have trickly hitech LSD like honda type r....otherwise how on earth do you put the power down.....

ok, well i have the mag. and yes they do have the figures as-

astra 0-100= 5.29 seconds and 0-400m= 13.42 @ 176.8kmh

xr5t 0-100=5.41 seconds and 0-400m= 13.52 @ 174.9kmh....

however if you read through the article it says the astra does 0-100 in6.7 and the xr5t in 7.5 and across the 1/4 mile are 14.75 for the astra and 15.38 for the xr5t. this got me thinking that someone had cocked up. so i flicked through for another 6 or 7 pages and come across a comparison of the bmw z4 m roadster and the mercedes-benz slk55, and do you know what? guess what the performance times for they are. thats right, bmw z4 0-100= 5.29 seconds and 0-400m= 13.42 @ 176.8kmh and mercedes-benz 0-100=5.41 seconds and 0-400m= 13.52 @ 174.9kmh

so there we have it. they cocked up after all.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
