whp estimate

[builthatch]

i am very versed in dyno tuning, stand alones, etc, but am very new to the ms3.

though all dynos read differently, i am curious what a properly designed 'cold air' intake like the cp-e unit combined with a second cat deleting test pipe on an ms3 would yield in terms of ballpark whp on say your typical SAE dynojet.

it's interesting to come into a niche that is on the ground floor vs. the honda thing that has gone from nil to bil over the past 10 years. the bad thing is there are not as many proven formulas with long term mod reliability data.

You're looking at around 280ish to the wheels.

 

[Derek88]

With my MS CAI and PG Test pipe, I made a conservative 248whp/281wtq.

This was on a dynojet that isn't the highest number thing...

 

[palerider]

Derek and I made the same numbers on that dyno. Ive had just Vibrant midpipe/catback, and Ms Cai.

That dyno makes low numbers. Others make high. Bottom line is you'll make sizeable gains on whatever dyno you use over stock setup.

Im less interested in total dyno numbers than ever. I want to see GAINS.

For what its worth... our dyno is the one where the Cox team made 343hp and 408 trq on their Caliber at 25psi I believe. I am scared to see what that car would make on some of these dynos that are showing 280-290 whp for MS3s with intakes.

Generally, dynos that read lower are the ones that support higher horsepower. Just remember, dyno's dont me jack, ET does... Ive seen my share of dyno queens and their ETs certainly dont prove their so-called power. Supra's come to mind...

You know I was talking to the driver of that Caliber yesterday back up at the shop, and he mentioned that some dynos do better, or worse, with turbo cars.. something about programming for load and then wheels slipping if its not programmed right.

Does this make sense?

i guess it depends if it's an eddy current dyno or not in terms of load, but regardless this is partly why i prefer dynapacks. the consistency from run to run is great and you never have to worry about sitting a bunch of dudes in the hatch of a high hp supra or rx7

haltech- turbo hondas come to mind as well; i've seen so many 400-500whp hondas run 12's with stratospheric trap speeds and mid 2 second 60fts...

guys, thanks for the info so far.

but, like i said, i do understand that dynos are solely tuning tools. if someone has a baseline, and added similar parts to what i mentioned with a resulting number, then i can gauge pretty easily what it'll do in terms of gains. that's really what i was looking for as oppoosed to an ultimate number i guess ; )

I'd actually say that trap speed means more about power than ET.

 

[builthatch]

I'd actually say that trap speed means more about power than ET.

exactly- thats what i was saying above about the hondas running 12's but having incredible trap speeds.

 

[Haltech]

I'd actually say that trap speed means more about power than ET.

Wheel spin accounts for high traps too... But if your car hooks, your et is going to be lower and more significant than mph.

 

[ill_eagle94]

A bit of wheelspin does generally make a higher trap but if you're not making traction, you're not going to make a good trap. I'm sure blowing the tires off the car for teh first 2 gears just because it will do it is not going to make you trap any higher than if you got a good proper launch.

Im putting down about 268hp and 281tq with those mods on stock boost.Mine was done on a dyno jet when it was about 75 degrees outside.You can check out my youtube page for videos of it.

 

[allmotor95pgt]

i made 290whp 311wtq on a mustang dyno.
my mods are mscai, open downpipe, cpe standback @18psi.

 

[nig3]

realistically between 250 and 260whp and like 280wtq.

 

[driver311]

On stock boost and those mods my car made 260whp. Stock it made 238whp. I picked up roughly 20whp with those two mods. I think my torque was around 280ftlbs. if I remember. Boost was holding 13psi and then falling to 10.

True, et will be lower all things equal, but trap speed is a much better indicator of how much power a car is making. ET is a good indicator of how good the driver is-again, all things equal.
