Right, the AUX port actuator won't work with the dp in the way, which is fine for my setup and I'm sure Jamaal will leave his open too with this setup...
You're right... lol but...im going to listen to Elliot and Jeff and get used to having 360 on LOW tune...hahaha
Needless to say, I'm pretty pleased with the results.

We have some decent film but the car still needs to be cleaned up a tad before delivery. We did have time to make a quickie though...

Dave I'm curious to see how your car performs due to the slightly smaller compressor. No doubt fuel might run out. We are doing some digging on a promising solution though.

Congrats Jamaal, it's not a slouch anymore....

Incorrect.

The SSV is operating in its normal manner (opening along with the secondaries around 3800 RPM).
In the 360 HP run the APV is held closed. In the 430 HP run the APV is held open.
In the future, when Turblown designs the next generation kit, we are hoping to have a functioning APV, allowing the best of both worlds.
In all runs, the VDI is kept closed. The VDI only causes a drop in power in FI applications.

Nope. This is right where I figured the end of the road would be (450 - 500 g/sec). It is definitely nice to see that good manifold design and a large turbine can get us there.

More torque is ALWAYS better (except to sell performance parts). The car with the greater total area under the torque curve will win everywhere.
On the track and street, the 430 HP tune would be a dog (comparatively).

agree with Jeff for many reasons on the dyno graph reasons. Thats been my goal the entire while. I may have to try and keep my apvs shut also.
And this is on a 10:1 cr engine---right?
Damn! Fine job dudes, fine job.

Now if the engine can last for 30-40K miles---then WE HAVE A WINNER!
Sweet.

Fixed. intrested too as are many many others are as well.

Congrats for sure! just don't foget that premix.
BTW what ratio is currently being used for "Jamaals Monster 8" ?

Well, since the OMP is deleted, he should run ratios consistent with past rotary recommendations.
I'd go with 128:1.

30-40k = lol unless you dont ever go into boost

that power level was achieved several years ago by Diasio using a GT35R in a prototype kit/race car chassis, but the engine won't last long (in street mileage terms) running at it. You have to consider it a race engine that is replaced on a regular basis.

So now that your finished with the tune does the tubular Manifold make the difference with the setup vs the Log manifold, or is the turbo selection the difference? or does water injection allow for a more aggressive tune?

it took esmeril 16psi to get 416 @7k
it only took 10psi for turboblowns kit to hit 426@8k

how much boost are they running to get 360hp

and is the water injection there for safety or did you tune for it?

I am not disagreeing w/ you about power under the curve. I guess its a difference of where we shift. On the track I am never below 5K and shifting at 8500-9 therefore the 430 graph is more useable IMO. On the 360 graph there is no reason to rev the car above 7500. Its the same way on my speed6, its pointless after 5K. Might as well be a 4 port if you are going to shift at 7500.

No - I'm looking at what the curve would look like if you opened the APVs in the normal way and combine the two dynos .
For the 3071 dyno - was the engine loaded up before the dyno began - like you did for the Turblown ?

This is a gratuitous and baseless assertion.

12 PSI. As is usual for this place, flow and pressure are being interchanged without and understanding of the difference.
I think this example at the dyno is wonderfully illustrative of the reason why you cannot ever interchange the two.

The former.

Yes. I use load-based dynos.
The Turblown setup was tuned on both Dynopack and DynoDynamics systems.

Enjoy your higher engine temperatures.

OK - you win . LOL So it was a steady 12psi from when it reached peak ?

I am pretty sure it was 10psi that entire run.. But guess what we are going back in two hours!!

The APV open run was 10 PSI.

The APV closed run was 12 PSI.

I think. lol

I cancelled the dyno time. We had a boost a pump on the car not working, just fixed it.. Figured why not see what adequate fuel pressure would do.. We will just do it on the next car

I have to ask a dumb question. What is changed in this engine to allow that kind of airflow?
On the intake side it looks oem?
Are ports oem?

Wow. Amazing. So it seems the engine isn't a restriction up to 400 whp. Funny that most have been running smaller turbos which is what has been the restriction to power output.
