Sorry if I offend anyone, but I came...

Ha ha. I so wanted to turn up the boost even higher but when my logs showed 100% injector duty and even at this boost level it was too lean for maximum power.

I think for now we'll hold the power level we're at and get back racing in TT3 or TT2 to finish out the year. Hopefully the transmission will hold up but I do have a spare we bring to the races just in case.

I wish I could get some video of that car. That clip was amazing.
Assuming it holds up and is somewhat reliable you guys may have the most legit race ready 86 setup.

Thanks for sharing details about pressures and other things for those of us who double duty the car.

If I remember correctly, when you first did the Hydra, you were only on port injection. Is that still the case?

Wonder if na would make power with just the head port, springs and valve angle job..

In another thread about lightened flywheels and pulleys, I read that some have found that running lightened parts on both ends of the engine (lightened flywheel AND pulleys) caused failures of bearings.

I wonder if there's something to be taken from that on a high rpm race engine.

Maybe a harmonic balancer?

Of course it will, but the gains would be much larger if it had FI. Doing that always helps though (assuming the porting is done right).


For me, there is no glide in pulse and glide :p

Looks like they're getting 240-250 hp with higher compression, ITB's and other mods.

We only ran that in the very, very early stages just to solidify the DI was a huge advantage and it is.

Now the Hydra EMS runs both the direct injection and the port injection along with quad variable cam timing, and full CAN support. So your ABS, stability control, all dash functions etc remain but the biggest asset is the fact that you can fully turn off the "stability control" and have a fully programmable traction control!

The direct injection and port injection strategy is also different from OEM and really allows me the freedom to change very specific ratios of "port" to "direct" injection at any boost or RPM level.

The flex fuel support is also very awesome because it switches fuel, timing, boost, starting, closed loop fuel tables, and more when running full E85 but when you taper off the ethanol it automatically alters the maps until it finally fully switches to the pump fuel mapping.

Very cool!

I just need someone to say, "Phil, I'm going all out NA, build me an engine."

Yes there would be significant gains with the head mods even NA. Probably NA would benefit more with some cam grinding also where the cams are pretty aggressive already for boosted applications.

No they just aren't as smart as we are. Oil pressure is the issue, not lightened parts. From the get go with just pictures it was obvious that we would have high demands for oil pressure. Unfortunately it took a lot of R&D to get the oil pressure we needed.

I'll be moving onto our external oil pump shortly and then the dry sump. We already have it all and just need to start making brackets etc.

Thanks,

There is no mention of ITBs and in fact I am rairly sure under the R3 rules you have to have a single throttle body. Also the quoted power figure is at the flywheel not the wheels. Someone with full bolt ons and a tune is probably already making similar power at the flywheel. I suspect the rally car has a nicer power curve though.

Looking at a built FA20 block, this quickly becomes a very very expensive build. Can this be a sticky?

Phil, I'd love to hear a price quote for all that work, but I'm scared im going to have a heart attack.
