fp black power curve

[caged]

Evo 9 with std 2l block cam and springs with a second hand FP black. Mivec makes the most impressive power curves, no way in the world I could of done this without it. 335kws isn't bad for a std motor the heads never been off. It did it on next ups Dyno which is one of the only brutally honest dynos up here.

shit thats around 450hp, what was the torque output? thats awesome on std gear!

 

[Bryce]

Thats awesome on standard gear!

i want your engine!

Its setup so it only runs 25 psi at peak torque and ramps up 30psi at 7000rpm, keeping the torque down at peak torque is the key to keeping them alive. I can't remember what torque it made.

I turned the boost right down yesterday because the driver was only just getting use to 270kws and the 335kws was making the driver nervous at the tight mt cotton track.

That's the one with the Ally exhaust? Sounds alright.

Yea I made a small alloy muffler for it too, I was worried about the noise restrictions at lakeside on the W/E, it ended up being quieter than the stainless on that came off and the muffler is straight through with no restrictions.

Is that with ecuflash?
Pulp?
1000cc injectors?
Maf or sd?

They are awesome engines. I was reading about a guy. I think he is low 10s on stock unopened motor. Bolt on mods only

yea ive kinda heard 400's the magic number ya dont wanna push past,
car sounds good man, esp. in that valley

^^Yep 400 ft/lb is the "magic" number for stock rods.
Great setup there, there have been a few Evo's making ~330kws on stock block.
Best to keep the revs up and be lower gears when accelerating.

Very nice figure, was that on PULP98 or E85??

My mates EVO2 stroker made same power with his GTX3076R on PULP98

Im quite impressed with the newer 63T engines now

Its a really basic setup and tuned fat with little timing as it purely a circuit car with rego just to comply with class rules. Its on united e85 because its only $220 for 200L, way cheaper than Caltex E flex. We run the bosch id2000 style injector ($530 for 4) controlled by a vipec and injector duty cycle of 66%. We had a 320lph deatchwerks fuel pump but ran out of pump at 280kws, no we are on a 450lph walbro that is duty controlled via a solid state relay and the vipec to reduce flow a stop heating up fuel for no reason and allows us to run std fuel pressure reg. I'm about to build a 2.3l stroker and a high comp long rod 2.4l as a spare. John from next up is a gun on stock blocks, his r32 gtst runs 9.0 on a stock bottom rb25 and 255 street radials.

What type of solid state relay did you use?

Nice work on this one.
Impressive!

 

[4piknup]

I was going to google this.
So you can run the pump at say 30% duty below 1500rpm?
Is that right?

from my understanding, basically you use an pwm output from the ecu to control the solid state relay which provides a variable voltage to the pump.

so you can create a table to have it run at low voltage at idle and full voltage at wot. you could even eliminate a fuel pressure reg by using this method.

I was really surprised how sensitive it is below boost /sub 2000rpm. Its a 100Amp dc/dc jaycar solid state relay ($47) with a 0.18v voltage drop at 100% duty. I just run it off a general purpose pwm output @100hz and have the table axis as Boost vs Rpm and run as low as 30%duty (around 7volts) and ramp it up to 100%duty at around 7psi.

The best bit was the fact that we got the fp black for $600 with low hours on it, sold the std evo 9 turbo for $600, sold the dump pipe we got with the FP black for $250 and sold the plasma man cold side outlet pipe that also came on the black for $200. Winning??!!

good plan, I actually log fuel temp and have some data on fuel temps. I have logged two different cars with interesting results. on my car I run an external lift pump (carter) and two external 044 pumps and a 7 litre surge tank that the rail returns too. I hit a max of 17 degrees (5 degrees above ambient).

In the other car (evo 7) it had a stock tank with a 255 lift pump and a sard fuel pot (10litre?) with twin 255s the fuel would be around 44 degrees (20-24 above ambient)

yep, winning

solid electronic relays are also silent make me want one for a particular relay inside my cabin that keeps pissing me off!
