75KW equals out to about 104hp yeah? Its respectable, quite respectable but as you said theres got to be more hiding amoungst the miles of tubing !

Im not very knowledgable on dyno's but what rpm do you run it up to? Or is it done on speed?

How big's your exhaust/dump pipe(s)?
Dave

edit: how many runs you get?

I'm very impressed Michael.

That's some awesome figures.

Remembering that my old CA18det with 180,180,180,110psi compression, only managed 78kW at the wheels, and I used to enjoy that.

Go the Turbo'd A Series!

I think with some hours spent tuning the injection and ignition timing you could gain some more horses, what diff ratio and transmission are you running? maybe you can run higher boost too......maybe it would be safe to keep it at it's current level too so tell us what is it like to drive

the turbo back exhaust is terrible, with no consideration for waste gate flow at the back of the turbos, and a tiny 1.75" system from the meeting point back im sure theres a decent number of KW's hiding there

and injectors are still maxing out at 4000rpm

i'm glad to hear others are impressed, im getting happier with it

it drives really nice, as you can see, power as soon as the foots put in, drives like any other injected car, and with the new block it revs out quite strongly, which is why i thought i'd get more power

im running a celica 5-speed with 4.11:1 h190 diff,

as this was a dyno shoot-out gear ratios and similar are not taken into account, i think thats why there's no torque curve

edit: 4 runs, best two up there, they control the car, they watch the curve and back off as soon as they see power start to drop off, not sure what revs was at

whoooo yeah that 1.75 inch will be costing you a good sized chunk of horse! what will you go up to? probably be ok for a 2.5-3.0inch single set up, I hate exhausts they can be so damn time consuming! when you fix the exhaust set up I think lag would be reduced heaps and you would get a bucket of midrange, can't wait to see more of it when you get it sorted out the way you want it, what injectors will you try next?

good work! nice figures especially considering the current exhaust setup!

should be an interesting match for my 12a since mazda claims 114rwhp and my engine is a little tired...

should have lined them up on the last cruise... oh well..

always next time....

just up to the posted speed limit of course

most people are suggesting 2.25" is the go

moved old dyno chart to top post

Boy, aren't we the kindler gentler forum that 12rc feels comfortable to post this.

If you are real nice, I might bring out the 44hp A15 dyno graph!

Damn stuck dizzy!

looks like it 'comes on' at about 105kph in 4th gear?
what's that, about 3500rpm? higher if you've got a lower diff ratio than the standard 3.9

With a turbo, the dump pipe off the back of the turbo can't be too big. I can't wait to finish my new engine, and run her on the rollers.

gosh my A series was 106hp at wheels with 40mm webers porting only on intake 54/86 cam and 2.5 system.
Id say a 2.5 to 3 inch system will REALLY help here I would say at least 20hp alone with that mod.

Nice power figures.

I note that the HP is up about 46% more than the previous mildly modified A15. However, torque is up a whopping 132% -- no wonder it feels so fast -- it is fast. Torque is what accelerates a car.

man that is a tuff looking setup that obviously works well. the only downside is when it comes on boost it is choking on fuel!

i would guess there would be another 10kmh(whatever revs that equates to) earlier boost by pulling some fuel out of that area. then it will look alot stronger there and i would guess another 7 kw as the top end is dying off as the fuel side cleans up so i am guessing the peak to be further down but not shown due to fat mixtures.
i can imagine it would be a fun thing to drive too with the hp coming on so damn quick!! once did a car that doubled its hp in 300 rpm now that was an experience and can only imagine you are having the same fun!!

fully sik bro

"and injectors are still maxing out at 4000rpm"

If thats the case..how come your AFR is rich as all buggery all across the board???

Also which is the 3rd gear run??
