Making use of my awesome math skillz, with 4th gear ratio to get the rpm and the hp/tq relationship I give you this:

In all honestly that's no likely to happen. This dyno plot was done at 16 PSI which is much higher than the shipped kit is set up for. With time, money, and a good tuner somebody could do it probably, but IMO people that have those things will be looking elsewhere to begin with. The flow map for the turbo they are using was posted in another thread, and at higher levels of boost it is definitely capable of feeding the engine enough air to produce this kind of power if the tune is nailed down. Depending on supporting mods (cooling, meth injection, etc.--none of which are included in the kit) I would also seriously question reliability at these levels.

As for the missing information on the dyno plot, they said the RPM pickup wasn't working, and I guess they just chose not to put torque on there (although those can both be derived from the available information with a bit of work). It would have been nice to see AFR as they claim the lack of power on the top end was due to the tune being off.

10 gallons of leaded race fuel and the (assumedly) same cold plugs and it could easily replicatable assuming that what's being posted here as far as the dyno graph is concerned is truthful. You've mentioned the flow (compressor) map of this thing: where is it? Is it just a regurgitated Turbonetics T70 compressor map? I wonder if anyone who's purchased one of these has removed the compressor housing and measured the compressor wheel...

The RPM pickup I could agree with. It's happened to me several times. However, if the AFR's actually went into the 9's, it would've flooded the motor, blown spark out, and caused it to knock which would've showed up on the dyno graph like techtonic spikes during an earthquake. Been there, done that foolishly, too.

They said earlier this was done on pump gas (93 octane). I believe the posted compressor map was just a Turbonetics T70 map as you say... I doubt anybody has bothered to measure the compressor wheel.

That turbo is definitely not a Turbonetics big-shaft, full T4 T70 so that compressor map can't apply. I doubt a genuine Turbonetics T70 turbo would even fit in there in that same position. It looks more like a small-shaft T3/T4 hybrid w/ a smaller-than-70mm compressor. I've seen this same approach of using different compressor maps being used in both eBay 'turbos-for-sale' ads as well as other peoples' posts regarding whatever (x) turbo they have. I'd like to see the specs on the compressor wheel. I'd be able to identify exactly what it is and how much realistic power output it'd yield.

The comment regarding race gas was to add an enormous amount of reliability so as to enable the possibility of another 8 owner w/ the same turbo kit cranking the boost up to 16psi and trying to replicate at or near the same power/torque output as what is claimed in this thread.

Also, there is no such thing as a "conservative"tune at 16psi of boost using any pump fuel alone with a 10:1, high compression ratio, zero overlap RE engine.

We were using our Esmeril Ignition upgrade so it can easily burn fuel in the 9s AFR...with stock coils it cannot be done. It was getting rich because we were in the dyno. We could have tuned for it but the car is street tuned where it runs fine and we didn't want to push it any further that day as we got a number higher then we were hoping for. We will hopefully be able to make a new video to show this on the street...we may soon have to put on winter tires to do so

Dyno Video was recorded...we have to dump it from the camcorder and upload it.

See above, our previous 366whp dyno was with the upgraded ignition also, see here for more info: https://www.rx8club.com/series-i-major-horsepower-upgrades-93/esmeril-dyno-out-box-155067/

Stock gearbox with upgraded clutch plate. We are seeing some slipping of the clutch at over 400whp. We already have something new we are putting on for the next step but we will retain the stock gearbox...it holds just fine (driver dependent of course )

This is with the stage 1 fuel upgrade that comes with the kit and will soon be available for purchase separately. One difference is that we took the stock 380cc secondaries that were removed to fit the kits 1000cc injectors and placed them in the primary location (primaries are only 290cc for a total increase of 180cc)...anyone with our kit can do this right now you will just need to tune accordingly. We will be posting instructions to do this on EsmerilRacing.com but you can just follow the RX-8 shop manual for now.

Best Regards,

Jason

I believe Mazsport uses something similar for their turbo kit, and the output from that kit and the Esmeril kit look fairly close to each other at the same PSI, so you could be right.

Maybe one of the boys over at Esmeril would be kind enough to shed some light on the subject?

I'd like to see it. Consider me skeptical. I like to critically analyze this stuff because in my experience I've seen alot of bunk being tossed around especially on the Internet.

Thumbs up

That is absolutely astonishing. Great job...

I wonder how reliable it will be if it's kept at 16psi's? How many miles can be put on it before a rebuild is needed?

I ask because I'm starting to contemplate getting the BHR turbo kit...

it's gotta be brutal to keep it that high regularly, I don't think this is meant to foster hope of driving around with a 400WHP rx8 daily driver, it's just a new best for the kit. They didn't even try to fine tune that run, they are keeping their street tune. Probably risky business. Maybe with those new apex seals their website says they are working on it might be another story :D

Chris will be in tomorrow. No one was working this past weekend...it was snowing so we halted street testing for the entire weekend....what little traction we had left was gone

Ok will this be put in on the dyno compare thread? How was it that you guys got it to 16psi? I hope you also update your website. Well I see you did! You are just going to have to give us those video's fast! I would like to see the TQ curve on this more clearly.

I'm wondering what kind of timing advance they were running. Probably like 4 or 5 degrees leading advance with 15 split, or that's what I would do at least.
