Routes to 500 whp?

[suicidaleggroll]

How are you making those numbers when literally everyone is saying it would require mods and meth or ethanol to get there? I'm not calling bs or anything, I'm genuinely intrigued.

Because that dyno is 400 whp and OP asked about mods to hit 500 whp?

Every time someone asks for 93 only advice, everyone jumps on the methanol bandwagon. What about just 93? Some people literally have no interest in running anything but.. which is incidentally what the OP asked.

Because OP asked how to hit 500 whp on the stock turbo. That means high octane/E/meth.

So- yes. an excellent tune on a slightly juiced dyno will make 500hp on stock everything (just DP) for whatever reason, I was assuming locked ECU- and given the questioned assumed no unlock.

This is why I really don't care about numbers and didn't bother with the "final numbers" print out from my tuner.

One big thing to keep in mind is that the dyno in CT where I had the tuning done is for all intents and purposes at sea level, and the tune was done on a 50 degree dry sunny day in March in an unheated dyno bay.

Conversely I remember when I had my old STi dyno tuned on an FP Green turbo in Colorado at a place that's at 5300' above sea level on a 95 degree day and didn't make 400 WHP. I was so bummed out until I actually started driving the car and was like "HOLY F*** THIS THING IS A ROCKET SHIP!"

I actually asked Mikey to mellow the tune out a little from the picture that I posted so torque delivery was a little smoother and not as peaky.

Yeah, I specifically mentioned adding ethanol fueling in my quoted post to make it to 500 WHP.

The reason why I posted what I did is to show that you can achieve really good power on the factory setup with just a good dyno tune. Spending upwards of $4k-$5k on "supporting" mods like CBE, catless dp, intake, charge pipe, doesn't really get you much beyond that.

His last question seems to suggest he wants to know what can be done without exotic fuels. So if 500whp is not possible with 93 which is what your saying, what can be done with it?

Ethanol and Methanol are not "exotic." M5 has nitromethane in it, but you can make 500 with boost juice. 50/50 water and M1, which is pure methanol.

low-mid 400s

Yeah these cars make decent power with a tune.

CBE, intake, and charge pipe do nothing. A downpipe absolutely does though.

because of the title of this thread, anyone researching will click on it, so i'd like to summarize..

cannot achieve 500whp on 93 oct (and mods) alone, hence why methanol and ethanol are being mentioned.

downpipe adds power; intake is a preference; aftermarket chargepipe necessary if going meth, nitrous, or bigger turbo; exhaust is a preference but can be used for weight reduction purposes

turbo inlet pipe and downpipe help with throttle response

Am I missing something here? I thought our supra on a dyno stock put almost 400hp and with an unlock and let's say MHD stage 2 on 93 with even just a high flow cat was around 440-450. On here guy's are saying low 400's with just 93??? I'm about to get my unlock done and going to stage 2 MHD ans I'm expecting 440 or so hp and over 500tq with just a AA downpipe and intake which really does nothing I know. But from what I've seen from good shops those are the numbers and you can bolt on a hybrid turbo on 93 and hit 500hp.

A downpipe absolutely does though.

For what it's worth, Botti said a catless dp on the stock turbo on 93 adds maybe 20-30hp from his experience. He said it's just not worth it unless you're upgrading the turbo. He and I both come from Subarus where an aftermarket dp makes a HUGE difference, but he said the B58 isn't anything like that.

I really have no data to back that claim up other than Botti is what I would consider a subject matter expert on the platform. ?‍

My 2020 put down about 350hp/360ft*lbs on the stock tune.

Stage 1 with literally zero mods other than the dyno tune was about 420hp/480ft*lbs when he was done.

When I discussed future upgrades with my tuner he recommended a Pure-800 with a downpipe and a manifold. He said those mods will get me to about 550whp on a comfortable, safe tune. I'm not interested in methanol or ethanol so he recommended a turbo upgrade.

hi
Wes and i are 2020 supras, so we can get up to 80whp from the tune alone.
on a catless DP, we'd be 430-450

if you have an AA DP, that's a 400 cell, you can expect 5-10whp gain on it, even with a tune. the AA DP is not a high flow cat

My local tuner said for 2021+, a catless DP and OTS tune on 93 will land me in the 450whp/490wtq range depending on the exact car and such. I think some of these other replies are referring to 2020 models
