Sharing dyno results and giving kudos to paulclaude who helped truly wrap up my CSL conversion project.

A brief, recent history of dynoing:
Late 2019 - TTFS dyno&tune - max was 300 whp on their DynoCom. The injectors was maxed out and we knew there was an issue but unable to diagnosis it.
Feb 2020 - back to TTFS - Frank helped diagnose faulty air temp sensor readings caused by improper grounding on the spare DME grounding pin. We corrected it on the spot and final run was 323whp. The graphs looked good but unfortunately, I never took a photo and Frank couldn't dig it up.
Sept 2020 - I got in touch with Paul and asked for some further optimization. I found a local shop called Loudon County Exotics who has a DynoJet. I completed some baseline runs and sent to Paul for his evaluation. That's image #1 with the Sept 29 timestamp, and 307 whp. Paul pointed to the richer AFRs in the low RPMs and offered attempt to improve.
Oct 2020 - Back to the DynoJet with Paul connected remotely. Image #2 shows starting run for the day (which aligns with the Sept baselines) and ending run 2 hrs later. So, the starting run is with the TTFS tune and the end run is the PCS tune. The end result was better than I expected and I am grateful to Paul for significant gains with tuning alone. He gave his best effort to improve the AFR spikes but a ceiling was hit. AFR's are improved from where it was before the overall drivability is vastly improved. Very impressive, overall, from my standpoint.

The final tune was stitched together with the run #12 (best AFRs, green plot) and run #9 (peak power of 347whp, blue plot image #3)

Well done, Paul! The important thing to know is hardware is the same across all dyno sessions mentioned above.

Hi James. Just getting round to replying - not got much time these days for forum input as i'm busy at my own dyno as well as other tuning projects. Great to see the positive report and was a pleasure to tune it for you. Low down AFR's still needed a bit more work although looking better and not hurting power. I find the SSV1 headers tend to cause these swings at the lower end, especially when paired with 288/280 or other higher duration camshafts. Certainly the 35-40HP delta from your initial runs was a nice improvement, along with lift in the entire curve. Glad it's running well

there are enough uselss oil threads already, maybe keep the discussion here to dyno results of oils or otherwise....

Yes plz, relevant side discussions are perfectly fine, but let’s try to focus primarily on dyno results/graphs/etc. Thanx everyone!

It's almost useless to look at a lab report without measuring how effective the oil actually is. An oil could be a perfect viscosity yet doesn't protect a darn thing to protect your engine. They don't even test the TBN. These reports aren't much of a picture of what's going on.

^^ I assume that is KW to the wheels, correct?

Correct.

I second the above motion!

I'll have to dig out the video, however I had mine an a mainline dyno back in mid-2015 iirc. Was stock except the exhaust. Full system, euro headers (car is euro spec), no cats, section 2 three inch status gruppe x pipe, megan muffler. No tune.

Made ~265whp iirc.

For reference, I also ran the 1/4 mile around the same time; 13.37 @ 169kp/h (105mp/h)

Found the dyno graphs yesterday while cleaning out the glovebox!

Here's mine this week after installing my TMS Airbox and having Hassan tune it. I am very, very pleased with the results!

334whp, 252whtq on CA91 pisswater

• Turner box
• HTE custom dyno tune
• Kassel CSL spec HP DME
• Kassel MAP
• Turner underdrive pullies
• SGT ceramic coated headers
• Euro Sec1
• Stock Sec2 / 3

Nice results, thanx for adding to the data base!

On the face of it, yeah! I kind of expected a slightly bigger delta but perhaps I've found the next restriction.

The general consensus with euro tuners is that US (W)HP = euro BHP, we don't tend to use WHP figures.

So in comparison, a stock euro E46 M3 generally makes 315-330 BHP over here, a healthy car with an airbox and supporting mods generally makes 340-360 BHP etc

Can't wait to see what the restriction is

👍 Out of curiosity, since your oil sample is pretty consistent. have you tried amsoil?

I have not, I ran LM when I first got the car, and those samples didn't look as great.

Interesting comparison Crooked. So do you mean you each sample has 2 weekends of trackdays in it? I'm no chemist, but is increased molybdenum ( I assume is molybdenum disulphide) & zinc ( I also assum zddp) means increased wear protection with the redline? The consistency definitely looks good. I was just following the 300v recommendations which they say isn't designed for long change intervals. They recommended every track/race event or 3000 miles. I think your car is a track car towed to the track right?

Yes, the car doesn't see any street use. Correct, each sample is two weekends of track miles. I'm staying with the 300V because of the lower lead wear vs the Redline.
