A91 MT Dyno Results

[djf]

Here’s my A90

Femto unlock with MHD+
Remnant Omega 65 turbo kit
MAD catless 5” downpipe
MBRP catback
Spool FX400X HPFP
S58 injectors
MHD flex fuel kit
Clutchmasters 1000 series twin disc
Some other stuff..

Tuner: David Shoup

This hub dyno reads 7% lower than their dynojet.

94 octane - 537whp Mainline hub dyno ~ 577whp dynojet

this next one is on E40 at 28 psi. Map is conservative. Ambient is 95. Starting IAT 104, finish IAT 126

609whp mainline hub dyno ~ 655whp dynojet

Great numbers! How many miles total and how many with these mods/tune? Any clutch slip or concerns with the trans?

Any CEL issues with the Kenji 200 Cell on stock tune? Been starting to flip flop on whether or not I want to do a catted DP. Not out here to chase numbers but a bit more of an angry tone in the exhaust from a less restrictive DP would be nice

Zero issues with stock tune.

Impressive numbers!
Did you need to upgrade your fuel system for the Remnant Turbo kit or Ethanol? Or both?

FYI, that dyno is notorious to read high AF. Higher than Dynojets in the area. Curves look good though. ?

For what it's worth.

My 2023 6MT made:

235kw (315hp) at the wheels totally stock.
255kw (341hp) at the wheels with AA Downpipe.

This is in Australia where our Dyno's don't read stupid high like they seem to in the US.

2023 MT with a JB+ and an AWE Touring (non resonated) exhaust running 98RON (ULP93).

That's around 420hp and 405ft-lb for the US folk.

Great another "I dunno why your dyno looks like shit but my car made 5000 more hp on this dyno on the other side of the world with totally different gas and calibration" thread.

Great numbers! How many miles total and how many with these mods/tune? Any clutch slip or concerns with the trans?

14500 miles total.

11500 with the stock clutch, didnt have any problems.

3000 miles with the upgrades. No clutch slip whatsoever, however, there were issues along the way.

1. The first hydraulic release bearing failed rapidly despite install going exactly to CM specs and shimming instructions with an installer who has ALOT of experience with CM products. Break in was 800 miles and it failed during the break in process despite the car never being pushed, launched or going above 4500 rpm. So far so good with the second one.

2. Initially I had a set of stage 1 Spool injectors, however, after 4 hours of dyno and 15 revisions, we could not get them working properly, both my tuner and I suspect a manufacturer defect of some kind as this isn't usually the case with their products. We swapped to S58 injectors that have a full dataset(highly recommend a product with data), did another 4 hours of dyno + street tuning and everything was perfect.

The car was running so rich with the spool injectors that we had to change oil and spark plugs.

3. The MHD flex fuel kit needs a custom open wire posi-tap kit from BIMECU to connect to manual cars.

Car is currently sitting at 700 whp since we upped the ethanol mix to E50 and made the tune more aggressive. The LPFP is the limitation in terms of power, this turbo has alot more in it. Trans has handle it with no problems, although we are keeping torque low.

Impressive numbers!

Both

You don't NEED to upgrade the fuel system. But it's a good idea if you want to break 600 whp. Only changes so far in terms of fueling is an upgraded HPFP and injectors. For ethanol we did the flex fuel kit described above.

This is in Australia where our Dyno's don't read stupid high like they seem to in the US.

It's because the toilets rotate in the opposite direction, balances out the high reading dynos.

@RyanA90 me too ?

can you elaborate on this, this is the first time seeing any mention of anything unique needed for manuals when using flex fuel. It’s entirely possible I am just being ignorant, but I plan to run flex soon enough and didn’t realize I’d need anything other than what all the autos are running.
Thanks!

When you order the kit from any vendor you'll notice in the manufacturer part number an "AT"

You have to specify with your order that it's for a manual supra. Better to talk to someone. Or else BimECU can send you their posi-tap kit. Which they did free of charge for me since they manufacture both products
