Really Light Stuff Intercooler

[Thomasio]

Charlie - as you may be aware, you are involved in the development of competing products. As such, I won't be sharing my engineering data with you. I have a standing offer to do a live dyno test with you present, what more do you need?

Oh, and I know a guy who tested [INSERT VENDOR'S NAME HERE]'s product [INSERT PRODUCT NAME HERE]... and his lap times went down [INSERT ARBITRARY LARGE NUMBER HERE] seconds...

rls Intercooler heat soak:

P.S. Enough hoop jumping, I'm off to do some good for the world now...

I don't build or sell intercoolers, i do make tunes for people that do build and sell intercoolers, well actually more like full kits since an intercooler alone won't do much.
Tunes are the only thing I sell, but i understand your position, the dyno sheets you posted have the hp/tq points on them, i can use those, just easy with a bigger picture.

Particulary since because of the way the dynapack displays torque it makes it look considerably more prenounced a change than it actually is.

I can provide you with a larger screen grab, please PM me the best e-mail address to send them to.

charlie AT goth.am cheers

I'm curious as to why your peak HP are so low as well, normally when we test on the dynapack it reads higher not lower ? whats the scaler set too?

The larger IC will flow more, the W/I will cool more...there will be more power.

This is the answer...you just need to show them.

[charliex]

so are those dyno sheets, a 3.1 pulley, WI and a different intercooler ? is that the same setup for both sheets less intercooler, or is the first sheet a bone stock car ?, the torque curve looks different from first to second ?

[Smoky]

Thomas, what is the scale used for the torque axis? The numbers are larger than one would expect.

And the scales (min/max values) change from one graph to another.... but that isn't a huge deal since you can still see that one scale shows data dipping to a way lower number from one session to another ...just don't know what the numbers mean since they are so large (unless your car is making the most torque ever! )

[Thomasio]

Dyno sheets are OEM intercooler (otherwise stock) and rls Intercooler (otherwise stock). [Edit: oops, and rls Tubes]. All dyno runs were with stock paper filter.

I've posted dyons of rls Intercooler and 3.1" pulley in earlier posts.

The Dynapack auto scales those screens.

Torque curve can (and does) change based on resonances.

As noted by ace996, better flow, better cooling, more power. And before someone says that it is going lean, I remind the audience that short-term fuel trims affect the long term fuel trim, which richens the mixture both in open loop AND closed loop.

Great question... I'll have to look into that, could be a units thing.

[charliex]

Its on the wrong page thats why its scaled like it is, you want the flywheel torque graph page, not the torque and power graph page.

It is showing torque at the hub... those are raw numbers. If I get time to play with it I'll input the gear ratio, wheel size, etc.

Horsepower graph, of course, doesn't care.

[charliex]

no it isn't, unless you think you've got over 500 flt/lbs of torque at the wheel!

even though it says flywheel mode, it comes out at RWHP, try it and see.

It's a chassis dyno, there is no wheel.

[Thomasio]

This should be it... rls Intercooler flywheel torque... no more hoops today for me. Ciao.

uhh yeah, its connected to the wheel hubs, not the flywheel, its not an inertia dyno, and its not an engine dyno but it still runs through the transmission.

Then you should know that there is a torque multiplication, Charlie. Thus, the "raw numbers." Why are you so grumpy, Charlie?

Just sent you full size screen grabs to the e-mail address you listed above:

Why does it always come down to you thinking i'm grumpy or emotional would you like me to include some smiley emoticons ? , yes it needs the conversion settings, thats why i suggested using the flywheel page instead though it does depend on the way the dyno operator set it up, or is there something wrong with me trying to help you out with the right sheet/setup to answer other peoples questions ? With the correction factors in place the sheets are a lot easier for people to understand, since you know it needs it , why not apply it in the first place ?

You're not including the TCF/ratio or gain settings in the dyno sheets, so its hard to tell where you're at.
