Turbo/SC Kits Comparison Chart

[nonicname]

I would love to see torque curves, I don't care about HP on this car.

what I want is a flat to better than than flat TQ tho rare to find them jewels, flat is hard enough to find

as for hp I want a constant rise rate so I stay pushed back in your seat thru each gear

here is my Vortech SC dyno plot for 240whp BRZ


24.5 mpg driving like a fool, far better, like 26.5 when she drives it

Huehuecoyotl- Thanks for the graph, however if it's not an off-the-shelf offering then it doesn't belong in my chart.

Hey ft_sjo can you add the stock curve as well? I am aware it varies from dyno to dyno, but this chart is pretty fun to at least compare the different curves themselves.

@ft_sjo, did you want to add my best NA (203whp) run as a base for people to compare? I know this is an FI chart, but I think it would help people who are researching kits and their capabilities.

I'm trying to figure out the google chart api and how to use a google spreadsheet as the source data at the moment... once I do, you can add any data you want and select which you'd like to view/compare against. Might be a while before I get it sorted though, but I won't make any changes to the above chart in the meantime.

A small turbo kit isn't any different than a large turbo kit when it comes to cruising - the car doesn't need to boost to cruise at any speed below, say, 110mph. Just because the turbo will spin up sooner and quicker doesn't mean it is going to automatically. 33~36mpg cruising at freeway speeds is very easy to do (get to speed, turn on cruise control).

I'd like to know what mods you have to get 203 whp NA?

Or, is that e85?

Yes. I/E/E85/Tune. It was 186 with the same setup on 93.

I think we should make an E85 forum so we can filter out that noise :P

I would suggest keeping this pump gas as not every state has access to E85. The typical buyer of these kits will be running on pump.

It's funny, a local guy thought the same... until i showed him an E85 map. It had 5 stations within 5 miles of his house.

Most of your fuel is in oakland, and berkley unfortunately. Lots in sacremento.

85 map


Thank god i'm in IL. Looking at that map it's the E85 capitol of the world.

Agreed. When Corn juice is at 75% of all pumps nationwide, then I'm down.
Until then I'll rock 93.

Street car is on street fuel.
Different strokes for different folks.

just want to point out that our numbers shouldn't be considered finalized. We were having issues with the intake cam timing and weren't able to tune it. Once we have it sorted i would expect a 8-10% gain and earlier spool.
