282 whp/215 tq on a mustang dyno

149k miles on the motor

-turner CSL box
-SG catless headers
-SG catted section 1
-SG unresonated section 2
-SG SCZA muffler
-JB racing clutch and lightweight flywheel
-HTE tune

What does everyone think? Had to dump a lot of fuel into it as we were running super lean at first. Hassan was able to restore drivability, thing is a riot around the streets now.

More out of curiosity than anything, isn't this setup capable of much more? Is the limiting factor the tune? Or exhaust too restricting? Is this capable of 350+?

Its probably the exhaust setup.. Its very Frankenstein-like. I'm also pretty sure I have an exhaust leak somewhere.

Streamline/Haimus carbon airbox
Bosch 550cc injectors
Catcam 280/272 cams
Custom Performance Stepped headers, OEM euro cats & section 2, Eisenmann Sport section 3
4.1 diff

Aprox 312 at the wheels, roughly 370-ish at the crank.

Hassan did a phenomenal job live tuning it on the dyno, lambda is very good and car runs very nicely. Allegedly the mustang dynos in Europe are very strict when it comes to reported power.

Thanks - I appreciate the response and I am leaning away from cams at the moment. I have wheels and suspension sorted, but seats are certainly something I've considered if I can get them exactly how I want. I'm also thinking about a higher final drive.

Oh yeah, the diff. That's more important than any of the other stuff I listed. Gears + an upgraded LSD really make the car come alive in terms of driving dynamics and handling.

I personally don't think cams are worth it but 280/272s do make more torque in the powerband than stock. They feel crazy strong past 4K RPM. That being said, your money is better spent elsewhere (weight reduction, wheels, suspension, seats.)

Car: Australian (right hand drive, Euro-spec) E86 Z4M Coupe, 28,000km for 'stage 1' and 40,000km by the time I got to ‘stage 3’.

Chart 1: stock versus ‘stage 1’ of Supersprint V1 stepped headers and cat’d s-pipe and a tune by Severn which included data logging on the street and multiple revisions (this is the sixth iteration of the tune). Note that the V1 headers do not clear the steering shaft for RHD cars, so the workshop modified them to fit. Not sure how much worse they are after modification, but they did still make more power high in the rev range than the already very nice Euro-spec headers, even without a tune.

Chart 2: re-baseline dyno of stage 1 vs ‘stage 2’, which was the addition of SS x-pipe, Powerloop mufflers and an Eventuri intake. No re-tune for stage 2.

Chart 3: re-baseline of stage 2 but with the SS x-pipe removed (the rasp and drone were too much for me), the addition of the Karbonius OE style plenum and heavier wheels (BBS RG-Rs, which are about 1kg heavier each than the Advans I had on for the previous dyno runs) versus Karbonius CSL ‘race’ intake and Severn alpha-n tune based on quite a lot of data logging on the street and fine-tuning on the dyno (exhaust mods the same as stage 2).

I changed dynos for these runs simply because it was closer to where I live. Also, I had to superimpose the revs x-axis from a different chart, so it looks a bit funny.

Adding it all up results in about 17% power gain versus stock – see the summary table below. I have to say I’m tempted to do a cam upgrade but the cost is really high and I haven’t found any dyno charts showing the change just from 280/272 camshafts (happy to be corrected if someone can point me in the right direction). I have seen a dyno for 288/280 cams, but the gains were only from around 6,800rpm and I would really want power and torque increases lower than that or I would never notice. I'd love to see a dyno chart showing the change from 280/272 cams alone if anyone has one to share.

Is the last graph values at the crank?

No - they're all measured at the wheels, without correction to calculate crank hp.

Looking for feedback on this run:

• Trace looks lumpy 4500-5500 vs other smooth traces here, but car seems to run fine.
• Power tapers off at 7000RPM

I always felt Kassel 'phoned it in' during the remote dyno tuning. I was renting dyno time and Kassel took a loooong time between runs to get back to the tuner because they were busy with other customers...which got.. expensive. Does this all look normal to you?

Rebuilt S54 in E36 chassis

Thanks.

Nice. I'll be running close to the same setup except a full SS 63.5MM headers-to-exhaust (Dinan Section 3). Excited to see how it performs before cams.
