New do88 intake manifold

[_Sp1ral0ut]

Any updates on this Mani?

I took the whip out to Track I-95 and man, did this thing keep IATs down! I was really shocked.

I'll be posting results from mine in two weeks.

So used this on 1 trackday and 2 Time Attack Competition where one day was 28celcius.
And everything worked so extremely well.

Last year the car almost died in that heat.
Open the hood and the intake Manifold was cold.
Like magic!

I never got over 40celcius in intake temp with OG air intake.

Got so many other problem this weekend so I don't have more data:

3 Aug and 5 Aug I will be back on track then a got more specific number.

But can't be more happy with this product.

Never got over 104f on mid 80F day? Uhhh. Are we talking one lap here?

Max 2 laps on that day then cooling lap or going for tirecheck
But i will have more numbers on paper beginning of Aug
So take it with a grain of salt

Okay, makes more sense. Look forward to seeing more data!

Standard version fitted to this M140i. Tested at the track today, the highest IAT we saw after a 20 min session with several laps of hard driving, was 112F/44C.
Car is running a MHD Stage 2+ multimap with E40.

What was ambient temp? These kind of data points are useless without that.

Looks like it was 65°F out there today.

21 Celsius / 70 Fahrenheit when we startet the first session, dropping to 18-19C at evening.
He managed to run 7-8 sessions before the track closed.

Last time the owner had the car at the track, he was running with the standard OEM manifold.
That time, IAT got so hot that it went into limp mode.

Pretty decent. How about delta start —> end of a session? That’s helpful as well since these heat soak.

Example. Sometimes a manifold can have the IAT starting a session at 110F, if it only increases 10F to 120F at the end of the session, that is good. If someone on the internet just saw 120F on a 70F day, they would go tell everyone it sucked. They would be wrong. Those people suck.

A good manifold should only have IAT increase 1-3F during a multiple gear pull.

Anyone got some new data to share about the do88 manifold?

Black Friday 15% off, ordered the standard version.

Out of curiosity, how does that compare to the Wagner?

I really want to know if the MERA version using the garrett core is worth the extra 1k over the standard. On their website they have the exact same specs/features with the only difference is they state the MERA supposedly cooled 3C (37.4F) better than the standard

This is the comparison i did from their graphs:
23c = 73.4f (mera)
26c = 78.8f (standard)
~5.4f difference between the peaks.

To me, it wasn't worth $1k for ~5.4f difference.
