Just like I thought the k27 cannot hold that much boost. It peaks at 13psi early and then tapers all the way to 10.5psi.

Still a fun car with the 4.10LSD.

Todd

Is the line at the bottom of your dyno sheet A/F or boost? It is labeled A/F on the right??

And how about that E36?.....................huh...................huh,huh?

I wanna see the dyno sheets of those who claim 400hp.

This does go to show, the k27/745i setup is only good for low boost levels, otherwise, go another path

Son of a bitch . . . Todd's 745i makes more tq and hp than my car does. I need to get to work when I get home.

Todd, the AFRs look nice and steady, but a bit rich. How much you think you'd gain if it were closer to 12:1?

6-8rwhp

BEGI is on the very least amount of rise.

Duhhhhhhh....I did. It states Airfuel. The reason I ask is that the graph depicts what you describe the boost did "It peaks at 13psi early and then tapers all the way to 10.5psi".

I was wondering if you were referring to the graph. And thus the question.

Those AFRs' look just like mine. Hmm.

Doubt yours are that rich since you inserted the washer.

You are most certainly correct. But I wouldn't call the shim a washer. That would be diminishing its' true size. I rather call it " the snail prod"

todd will you be coming out with a replacement for the k27 for the guys with 745 setups?

Yep. Hoping to build a k27 with a Garrett 60 trim wheel good for 480rwhp.

Todd

estimated time of availability?

Todd,
Do you have the Tial wastegate adapter for the 745 available yet? Sign me up for one.

Hey Greg,

The are going to production soon. Shoot me an email with all your info and I'll put you on the list to contact as soon as they are ready.

Todd

with that turbo upgrade...

Anything internally going to have to get changed?

I see those #'s are SAE corrected. Can I ask what the correction factor is?

turbodan wrote:I see those #'s are SAE corrected. Can I ask what the correction factor is?

Sure.

It made 283/320 uncorrected.

276/312 SAE. So ~.98

Interesting, huh?

Todd

So your CF was <1?

turbodan wrote:So your CF was <1?

Yes. .98 Ambient temperature was 55F.

Todd,

Just saw the dyno numbers. That does not look right with 14PSI boost. If I recalled correctly the last 745i dyno I have seen from the 745i board was well over 325rwhp for 12 PSI.

I am waiting to get mine dyno'd if I can figure out how to get the Greddy E01 to work properly. The problem is the longer I wait the hotter it is out here in the desert.

Anyway, perhaps you have forgotten about it but I don't recall getting payment on the item I emailed to you. Drop me a line when you can. Maybe I can use it towards something you have.

Thanks.

I applied your credit towards the wastegate. Call me for a CC# if you want payment instead.

Afshin's car made about the same numbers at 14psi. The more important point is that my k27 wouldn't hold 14psi but only ~11psi.

Todd

Todd I have been waiting to hear something on the k27 upgrade and will be needing a wastegate upgrade. Any word on that?

I anticipate having the k27-60 available next week. The wastegate is going to take longer since my head of R&D is very busy!
