one boring dyno video:

and one odd looking dyno graph:

Before someone comments it. Those are newton meters and kilowatts

So it’s: 284whp @6400rpm
peak torque: 265lbs around 4300rpm
boost was only 14.5PSI
there was something wrong with the wastegate signal hose and I didn’t get more boost. Wastegate was fully closed (in Adaptronic EBC wastegate settings) but still it didn’t boost more. edit: turns out my wastegate lid was leaking

I have to get external mic for my gopro

But car runs fine. There’s odd small oil leak in oil pan and I don’t feel like re-sealing the whole oilpan. Maybe I just leave it.

And then there’s a usual E85 catch-can issue. I get about liter of water in one trackday. But there’s a little I can do to that except build super big catch-can

I'm pretty sure that dyno dynamics "shootout mode" means crank hp and not whp.
edit: Yeah it says on the dyno that the mode is "Shoot_4F". That's for 4 cylinder 2WD Forced induction flywheel "estimation"

No. Here's crank hp chart:

I'm only going to hate on the mouse trap. Get a rollbar if you're doing **** like that.

Car looks badass otherwise though, sounds healthy.

Yeah I know but at least i get quick painless death if I rotate it Real rollbar is in my shopping list though

Also I had to get better tires. Now I have Yokohama AD08 215/45 and they spin on third when exiting corner. I had never concentrate so much just to control throttle

BTW your air filter heat shield looks frikken fantastic. But it won't work. The heat shield itself will heat up. And radiate the heat to the air filter side.

Cold air intake is only worth it unless it is actually sitting outside of the engine bay like cowl induction. Hornetball does that and recorded good results

2560 is in there because it was cheap (400$. Almost new). We design that downpipe EFR6258 in mind. That is why there’s v-band adapter in turbine housing

You are probably right. But it isn’t too hot to touch after track abuse. Just a little warm

And IAT isn’t problem. My cheap (95$) china IC is doing good job there. Air temp before IC = +125°C. After IC = +28°C (max)

And I think it’s time for Deatschwerks DW300 pump. I’m now using Walbro 190HP and I can clearly see my fuel pressure fall from 80psi to 70psi after 6000rpm

Actually its fake 50mm Tial. Much cheaper than the real one: 50MM BOV with Tial Style Flange - Red (Type 2)

It came with two springs. One is so stiff that it makes loud surge noise every time you let off the gas. And the soft springs other hand is so soft that it leaks on idle. But I read somewhere that it’s normal to BOV leak little on idle. (that almost rhymes)

We have annual inspections here so I have to add resonator that look like a catalysator to the car




Exhaust has been making noise so we make more room for it by grinding diff housing


Now it has room to move

Can someone remind me why are we still using superchargers?



This is my current GT2560 setup vs. previous FastForwardSupercharger™ MP62 kit in the backround. If you're looking just boost level, at 2200rpm turbo start making more. Still I'm sure GT2560 is making a lot more torque above 1800rpm although boost pressure is a bit lower. It pulls like big turbodiesel engine. I hit my boost target at 2900rpm! and this is with BP4W head not the VVT one. f*cking awesome

GT2560 fifth gear pull: (rpm | psi)
1879 2.75
2022 3.48
2122 4.20
2276 5.24
2390 6.82
2456 6.96
2564 7.98
2662 9.72
2776 11.46 (wastegate opens)
2866 12.64
2996 15.38 (boost limit)

...$4695 for FFS supercharger kit? No thanks

ps. You guys should see the IAT temp log between turbo and FFS sc no wonder that I was able to break 2 engines with the supercharger
