**New Single turbo record**

Abacus38 · 03-19-2015, 04:08 PM

Well I guess we're going to have to wait till someone with deep pockets shows up to experiment. I know the injection windows gets kinda slim in the upper rpms but I believe it can be done. It has been done on other platforms already (BRZ/FRS) we just have to find somebody brave enough to do it.

My MR2 I rev to 9500rpm and it'll handle 10,000 no problem but power starts to drop around 8000rpm and pushing it past 9,500 is pointless

Motiv used a FP 6466 on their 829whp pull which the PT 6466's inducer measurement on the comp wheels is slightly bigger than the FP's but the exducer on the comp wheel is smaller. The exhaust sides the same way, inducer is bigger, exducer smaller on the PTE compared to the FP. I'm not sure what turbine housing they used. I went with the 1.0 AR divided T4 because I felt it would still have great midrange but not choke too much up top. Basically I chose my mods around the idea of making a really fast and fun street car. Usable power everywhere and not just one region of the rpm. That's the same concept I apply to all of my cars. I want as much area under the curve as I can get because to me, that is a much more fun street car.

Same reason I went 1.0 ar on my fftec 6266 g2. Felt like it was the best of both worlds...what's even crazier is the 6466 has spool charchteristics very similar to my 6266.

Remember HP= RPMs* Troque/5252. Judging by the these torque graphs graphs of these singles it looks like we carry to the torque up to 8k.

The motor has already been up to ~8300 rpms and that particular motor started having some issues after that. Simply raising an electronically controlled limiter will NOT allow the engine to handle higher revs mechanically.

I would add $100 also to see a motor go Pop and see what fails first. Someone should open up a Paypal fund to gather the donations and if we don't make it in a few months, rerun the money to everyone. This may not be the car to do it in since 6466 and already at 36psi. as long as enough boost, fuel, and proper tune I would love to find out the limit. There is a buddy of mine here In Houston with a 6766 setup he is about to tune with Jake remotely on the Dyno and he has everything in place to make big power. Custom big IC, all custom plumbing and exhaust, PTE 6766, twin scroll housing, AR 1.0, fuel it stage 3 and Motiv level 2 PI, 1000hp level 10 trans upgrade, etc etc.

Sammy? Can't recall if he ended up sticking with the VTT STG3s

No, Jason, he has a build thread on BB

Mechanically its a simple solution. The only thing you have to worry about mechanically is can the oil pump keep up and can the valve springs handle the revs. The main concern is fueling with the DI window. We can solve that by port injections.

Believe me, I'm well aware of this motor's short comings when it comes to what it needs. Don't let my post count fool you.

I'm not knocking you at all I'm saying is until we get more data out I'm not going to rule out 8k redline on this motor with PI. The only way we are going to find limits to this motor is to constantly push the boundary like the Toyota, Honda, and DSM guys.

Trust me, I'm all about pushing the limits however, I also want to enjoy the car right now and also hopefully lower the 1/4 mile record maybe into the single digits. The car has more than enough power, I just need to figure out traction with these cars. We are going to set up a boost by gear to help with that but I really think the suspension needs addressing as well to get this car to squat properly.

We will be spinning our built motor to around 8K to start, then prob go higher. Its going in, in the next few days, will take some time to tune, then I will beat on it like it stole my bike...

jonas · 03-21-2015, 03:08 AM

Very interested to see this car continue to do good things. It still amazes me that we can swing into the 800HP range for so little money compared to what you would be paying on other platforms!

I wish we could take this exact car and put a Fftech bottom mount kit on with the same turbo and see the difference in results and see which one is truly better. Because I was talked into getting a bottom mount turbo but this set up no doubt performs insane

No difference in bottom VS top. This graph and dyno proves it. Go line it up with Motiv graphs and you'll see. There is no magic in this kit nor the Motiv kit. All will perform within the same region of specs.

Abacus38 · 03-21-2015, 01:53 PM

What are the benefits of going top mount vs bottom mount? Could you fit that new pte 6870 on a topmount?

essex_lad · 03-21-2015, 02:19 PM

that is some serious F**KIN power!!!!!

Bottom mount will generate less under hood heat. Shorter piping equals less surface area to radiate heat from.

Good point, which makes the motiv kit more ideal for circuit racing. For half mile and drags I'm liking that fftec kit. I'm sure the VM will be equal to. I just don't want to push my engine that hard. This kinda goes back to my original thought of how well the vff900 would perform when pushed. That kit might be the best of both worlds
