199whp on 91 Openflash and Bolt-ons

[Luckrider]

That is damn impressive... but it looks like there might be that last 1 or 2 HP left on the table from coolant temp. It should allow the car to run just a tad more timing and might net the needed gain for the elusive 200WHP.

The tune is probably aggressively rich.

Spot on. About 11.2-11.5 at WOT. Could definitely be fine tuned

It is a mustang. From my experience with this exact dyno though, it actually reads a little low

It's supposed to read lower than DynoJets, but 199 in a mustang is high for a mustang. We're talking about REALLY high. By rough calculations that car would make 228whp on a DynoJet. Any adjustments or corrections?

mustang's have the capability to run in a "dynojet mode"

just so you know

Normally they run a calculated amount of power loss + power @ 50 mph thus reading low as shit.

Full bolt-on k20's reading 195 whp kind of low. 195 whp on mustang, 220 on dynojet.

If you look, at peak it made 36hp more than the stock car (granted different weather). It seems fair and if we use the stock car as having 170 (aggressive weather adjustment due to humidity and temp), then this is making ~240 crank which is still a 20% gain over stock. If you do an unadjusted measure it is more than 22% at the wheels.

Ok...

So what was base before these mods and tune on that dyno???

[DC2R]

Are there variations on how to mod snorkel? Been thinking about modding mine

See that's what I was thinking. I was actually expecting to see like 170whp or so. I'll talk to the shop again and ask.

That would sound about right. I put my car on a mustang recently and baselined 170whp on 93 with headerback exhaust, intake tube and drop-in. After installing a header the car made 177whp which would be about 202whp in Dynojet numbers, which is about in line with what people are making with similar mods.

Some setting had to be changed, hard to believe 199WHP while still having the stock front and overpipe.

I baselined 155WHP on a mustang dyno, and with a K&N Drop in, Q300, and 3" catted front pipe, my car made 167WHP on the same dyno, and it did 170whp on a dynojet... all on 91 octane and stock tune though.

good numbers, im dynoing saturday at rt tuning. OFT and revworks header but a 2.5"catback. ive completely remapped the timing and fuel tables so im hoping for over 200whp

[SirBrass]

it's totally possible to safely run 200 whp on a mustang NOT in dynojet mode with headers and front pipe/overpipe on pump gas, but it takes a very good, multi-iterative custom tune, not a canned one.
