ALDON AUTOMOTIVE DYNO TUNING SESSION 6/9/11





217 BHP@Flywheel
177 WHP
164ftlb

This is a 20hp gain on this dyno since it was last tuned!

The old results from DEC 2010 were:
197bhp
157whp
165ftlb


Its was later dyno'd earlier this year at HLM's dynojet with no changes and made:
202bhp
186whp
157ftlb


Notice how the dynojet gives a considerably higher WHP reading. I'd love know exactly what it will put down now on a dynojet...dare i even guess - I suspect around 225bhp/206whp.


I have since fitted/changed the following parts to get to where i am now:

KSR Intake Manifold
UR Crank and Water Pump Pulley
Sard FPR
3" Intake Pipe
Cam timing adjustment
Retune

As you can imagine im very happy with the results.

A quick snap shot on the dyno -

wwwoooowww

Not bad for those mods.

Nice power for a DE for sure. Keep up the good work.

More South African engineering powering the SR20s


Well done. I think a 200whp DE will feel a lot stronger to drive than a 200whp VE personally.

That intake seems to work quite nicely. Good job.

Cheers guys, yeah this was a good step forward in getting the torque holding further into higher RPM.

Im only revving out to 7450 and power peaks at 7000rpm.

I think a specced header (specifically, shorter primaries) for this setup will allow me to make more power at higher RPM, and i will make over 210whp/230 crank. I guess thats the next step, along with an 8000rpm rev cut.

The best part about it all, is that the motor is all cylinder head/breathing mods. I havent touched the factory DE Autech bottom end yet. It is essentially a bolt on motor thus far.

Small update:

The car just ran 13.84@100mph on street tyres.



I also ditched the KSR intake manifold, and went back to the stock one.

that car is sexii .

Congrats on the numbers that car is moving for a de. Any reason you ditch that intake manifold?

Yeah, basically i managed 14.4@96 with it on and a few dyno pulls later on a dynojet showed some considerable torque loss.

The graph below shows the old stock intake manifold (186whp/157ftlb) vs the KSR intake manifold tune (180whp/143ftlb)....

The KSR intake manifold will probably be modified and retested at a later date along with a different spec header.

For now and my current rev limit, the mazworx header and stock intake mani work pretty well together.
