Yes this is the 200bhp one - also known as the series 5.

wicked....so mildly higher compresion rotors? What sort of horsepower can you make reliably out of them? (i dont need to meet emissions regulations)

antnicuk · June 15, 2006, 10:04:22 PM

mine has 380 at the rear wheels (460 fwwp), with the series 4 rotors. I will let you know about relaibilty next week as i\'m driving to the ring.

off topic somewhat but what day you driving to the ring tony?

Brett · June 16, 2006, 08:08:29 AM

Dubber, you can make near 300 with the stock engine and turbo. (Depends on cooling etc and fueling) Is this going in the beetle?

antnicuk · June 16, 2006, 08:10:42 AM

you could see 300 with an ECU, fueling, charge cooling and a turbo with milds engine ports. There is some speculation on whether you can make 300 on the stock turbo. I think if you had a ported engine with the stock turbo you would see 300 ATW\'s. Or stock engine and a good turbo. Do both and you should see 380....

yep, 23rd, cant wait. Just got my eurpean sat nav sorted out in case i cant keep up with T2REW.

Cars not ready yet as i still have to fit my big brakes, nothing like cutting it fine!!!

8.30 eurostar if i remember correctly.

Brett,

do you reckon you would see 300 at the wheels or flywheel with stock turbo and engine?, i think you would struggle with 300 fwhp on stock turbo and engine.

Brett · June 16, 2006, 05:34:21 PM

I reckon you could get near 300fwhp with the stock tubby and engine, but I recon it would need water injection and a good map. Probably talking 1-1.1 bar boost too.
I was making near 280fw on the 1st dyno run, sadly we didnt get a print out until the 5th dyno run, by which time heat soak had knocked the power down to 250fw and 196rw.
Going on that evidence, with the fueling and the cooling I think 300 is posible at the fly, so maybe 250 atw?

dubber91 · June 16, 2006, 05:51:42 PM

wicked...well the engine is due a rebuild anyways, so i might as well give it a decent sized port (Its a weekend car at best now)
What ports would you recommend? Bridge? As its in a bug im guessing low down torque isnt that essential...

Sorry to hijack, but was that with any fuelling mods / increase in boost ?

Cheers,

Prof :cheers

ahhh was just wonderingas you might meet the uy with the supra from rotorstock there...but youre leaving on the day he comes back

Brett · June 19, 2006, 05:47:31 PM

Hi Prof,

That was with the following mods/spec

New engine with less than 5000miles on the block
3" Bore exhaust from the turbo back, going into a 4" box
Knightsports FCD
K&N Panel
Blitz BOV

Boost was all over the place like that (0.6 max in 1st, 0.7 in 2nd and 3rd, 1.0 in 4th, 1.2!!! in 5th) so after the dyno run I started looking around for an ECU, managed to get hold of a Panspeed sport tuned JDM ecu, tuned for exhaust and filter. That smoothed the boost out a little and brought it in much harder. (0.8 in 1st, 0.8 in 2nd, 0.8 in 3rd, 0.95 in 4th, 1.0 in 5th)
Panspeed rom combined with that exhaust totally transformed the car, with so much boost available in the first few gears it brought the 0-60 a hell of a lot

Had the probe up the exhaust a few times and leaning didnt seem to be an issue excpet in 5th on full boost it was starting to head for 1.0, whereas in most other gears it was around 1.1.
You need to speak to Retrobate as he has it now, but I cant state enough the difference it makes. Made it quick enough to see off a 92FD with a Cat back, many, many times. (Local lad, friend of mine and slightly disgruntled now)

Hope that helps, also, if you do a search for threads in this section started by me, looking around April time last year you can follow the build etc.

:wave

When are you going to do the new build then Dubber?
