Default Greddy Twin 446whp ?

Ran on the Dyno this weekend.



Greddy Kit.

I was under the impression that Greddy's were some of the "Weaker" kits to use.

Are these numbers normal?

that blue line looks weird, like someone was tracing the stock market more so than TQ.

Greddy kits make good power. If you are looking to go over 700whp then its not the right kit. Its great for stock block and the medium budget built motor setups.

Is the car an automatic?

Also, are you attempting to brag by acting surprised by the numbers your car produced with this kit? I don't know of anyone who knows what they are talking about that would consider the Greddy 18G kits weak. What are the "stronger" kits then?

Also, your numbers are in flywheel hp, we speak in terms of whp around here and note what make of dyno was used.

It does cross at 5250rpm, its just that the graph has different scales for hp and Tq...........which I hate.

You officially have the weakest Greddy car on this site. Good job.

That is hub hp not whp (no weight of wheels + tires = higher numbers), looks like a Dynapack graph.

I have never seen a chassis dyno that gives you flywheel numbers . For wheel horse power you will lose at least 10% so that puts you at about 400whp.....average power on a stock engine and not even close to maxing out the potentional of that kit.

At the bottom it says "power flywheel" I have never seen that before. It might do a calculation to get that number

Either way his "weak kit" hasn't even started to work at 400-450hp
