The Base Line dyno for the stock 1.6L we had was from an earlier dyno run and did not match up to our current dyno charts.

Sounds perfect. I bet they will sell a lot of them if the kit is as well sorted as it looks. Sounds like they fixed all the problems I've read about older rotrex kits (compressor too small, oil getting too hot for rotrex, cracked mounting hardware).

Having made my own DIY SC kit (and mine is no where near as nice as theirs), I can tell you it's wayyy harder to get it working well compared to a turbo setup. If this were for sale before I built mine, I probably would have bought it.

That don't sound right for the HP on your setup. I thought people made 300whp with 550s on gasoline?

Yes. These were all stock motors. TDR has a track car with a fully built motor running MegaSquirt. They will be getting it dynoed ASAP.

These examples are using piggy-back fuel and timing controllers.

I'm slightly skeptical of the dyno charts (mostly the 1.6), just based on what Mobius and a few others have done on more heavily worked over 1.8l engines.
TDR was as surprised as anybody. These are not inflated but corrected charts.

The idea is simplicity and no fuss. I can't wait to see what the TDR Track Beast dynos at. I'm thinking over 300 RWHP

Let's not go there.

Hopefully soon! The Fuel and Timing cards are actually pretty good though. Perfect for simplicity and safe reliability.

I'll post a log when I get back to my computer.

Found one. Attached. 220hp run. Dyno plot is somewhere in my build.

I even found the dynojet run file.

So what all size Rotrex's can fit on your bracket? C15-60, C30-64, C30-74, C30-84, and C30-94?

Are there prices yet?

I really like the position of your Rotrex oil cooler and I talked to William last week about you guys mirroring that on the other side with an engine oil cooler. How is that coming along?

I know we've used a C30-74, C30-84 and C30-94 with our bracket.

Looking at starting around $4700 with inter-cooler, fuel management, catch can, injectors, fuel pump, etc...

This is William! I believe Gary made the mirrored engine oil cooler brackets so they should hopefully be out soon as well.

If there's anything Tuning Done Right knows it's timing and fuel.

Looks like a nice kit for the DIY installer who wants reliability and not having to repair their car constantly.

How would a Rotrex and a coldside double charger system work? Might be a sick build if you could keep the engine in one piece. If you can twin turbo, who not a twin supercharger system?

Why not get a bigger supercharger if you want more power? Have you seen any twin charged DIY systems work well? I haven't.

How is a fuel card and 3* retarded timing reliable?

Yeah, I saw the FPR and timing retard tricks; someone, somewhere will drop a standalone into the setup and find another 15 horses without trying.

how does downshifting make up for the lack of about 50rwtq on all these plots?
