Dyno sheets and discussion for UK Rotaries!

[John Yorke]

Rollin road junkie here:D

Went down to Abbey Motorsport today for a comparison and ended up with 346.5HP @ hubs that equates to 395@FW Flywheel torque 291.2.

Very impressed with their setup highly recommended for your tuning.

Very interesting John, so you reckon about 10% difference between Dyno dynamics rollers and the hub type at Abbey?

Might see you at Godstone later

Hello there chaps,

had a dyno read at Thor Engineering on the hub version where your wheels are off, supposed to be very accurate.

The result was 341bhp running at 0.75psi on low boost!!!
                         251 torque

Which for all concerned means if the car was run at 1.1bar we would make 450bhp people!!!

The next dyno day this will be proven, i did not run to full potential/boost as currently have a coolant leak somewhere and didn\'t want to over do it.

Funny thing was a R34 GTT apparently 400+bhp ran 342bhp at 1.3bar!!!:rollin :rollin :rollin

That\'s really good power Max,Things are hotting up for rotorstock!!
You should be seriously quick up the 1/4 now.
Considering that Clive had 355 at the hubs on the dyno hub at Abbey, you have currently got a lot more power than he had when he did the 12.2 1/4 mile, and with your wheels and Drag tyres you should be able to easily do a serious 11 second time up the strip if not a 10 with your caz diff.
What gear did you do your run on the rollers in?
Tim may be going up a week on sunday,maybe you could go too?
Kind regards

\'Sideways\' Steve Cleary today at CPL on the DD\'s rollers:

330.3 rwhp @ 7000 rpm

Motor and GT35 (not 35/40) by Tim (stock ports, but with an -RE centre plate from recollection)
Intercooler and lots of other stuff fitted by Steve
Tuned by Geff

Smoothest single I\'ve driven, shame the car is a sack of poo atm due to lots of dead bushes

Steve actually came down today, what a lovely guy - great to see ya baby!

Cheers Carl

Well, the car appears quick, but is the driver up to the pressure - I guess that we\'ll soon find out!

Looks like Rotorstock will be major fun - with lots of cars now producing the goods

Rough spec of the car is as follows, probably missed a few bits!

Ported & polished, 2mm 2 pc Mazda seals, Garrett GT35/40 turbo, Apexi Power FC, datalogit, commander, SX fuel pressure regulator, 1300cc secondary injectors, electric water pump, Apexi GT front mount intercooler, air pump thrown in nearest bin, cat thrown in next bin, Greddy boost controller, NGK 10.5 racing plugs, magnecor plug leads, HKS twin power ignition amplifier, solid engine mounts, solid diff mounts, Kaaz 1.5 way LSD, Ceramic single plate clutch, Racing Beat springs, sway bars, Koni adjustable dampers, Porsche 993 turbo calipers and disks, Volk racing GT-7 18 inch alloys, Dunlop D01J r compound tyres, Feed rear box, Motec PLM lambda meter, Denso supra fuel pump, Bride bucket seat, Cusco carbon front strut brace, etc.

I vowed earlier today (with rotary witnesses) that I am now calling it quits in the pursuit of more power, so no more boost, enjoy the car as it is, it seems to like it\'s current state of tune. Any more work I do now will be purely reliability & tidying mods.

I shall take a peek at diary to see if I can go, should be a good giggle with Tim there to liven up proceedings!!

Max,
Great results!   Who tuned her for you?        I see you are running 10.5 plugs,  do you find they foul in traffic/slow driving? or did you not notice any difference?


With figures like that you should eat M3\'s, chew them up and spit them out again!
regards
tony

[clive]

Well done Max and all involved in your great result:)

RotorStock has just looked even a little better, seeing as your car should now be able to mix it in with the very best the Jap community has to offer:cool :cool
