OMG, cant wait to see how much improvement these are over the Ko4's... But at this rate I wouldnt expect traction until mid third gear
I have been having some really bad issues with my twin turbo setup so I decided to tear into it and look for an issue. Turns out when I pulled the down pipes off my flapper valves for the wastegate were missing lol They must have been launched out the tail pipe at some point! So here we go, one weekend, 31 hours of labor, and one amazzzzzzzing setup! Ennnnnnjoy!
oem maf's don't like "blow thru" setups.... but glad you went with a single turbo and not welding the turbo to the exhuast this time

This is better! tuning that AEM will be much better with a draw through MAF, A bar of boost will be fine lol
So I was driving home on Friday and noticed my car was making a clanking noise every rotation of the wheel so I pulled over and noticed metallic gear oil on the ground dripping. Awesome. I get it town apart last night and appearently a m6x1.0 10mm allen cap bolt got launch from in the bell housing, through the tranny case, into the diff ring gear then to the 1-4 output shaft gear. I am not missing any bolts anywhere on the engine and I have not installed anything on this car with the size bolt. I am stumped!!!!! Anyways I have a new tranny on its way...
Of dear! Unusual
Glad to see you have a new gearbox, uprated clutch getting fitted now?
My opinion is get a higher rated wastegate spring!
What were the k04's like on the VR? Did you find they ran out of juice above 6krpm? I'd assume you get much better top end assuming it's 0.82 ar or more when up and running?
I'd be interested to know how it compares to the ko's when you've sorted the issues
The K04's ran very well on the car and i never noticed them maxing out. When you think about it, the k04 is an upgraded turbo for the 1.8l engine. Each one of the turbos is only running with 1.4l of engine. Buutttttt the GT35 has an exhaust a/r of .68 and the compressor is a/r.70 with a 63 trim wheel. It is such a huge difference it is not even funny. By far the gt35 flows so much more air and you can feel the power difference, even at the same PSI. I will be running this weekend so count on some awesome videos!
Get it screwed upto 15 PSI, thats what im running with the same engine
Hmmmm what do we have here? Oh yes thats right SEX ON WHEELS Also check out the new tanks I added to replace the windshield wiper fluid, powersteering fluid and coolant overflow. These are Camco generic tanks that are perfect for custom stuff.

cool, just need some jubilee clips now on that silicone on the turbo!
So I have done some research, the standard fuel pump will only flow 90 litres per hour, thats 1500 cc per minute, so effectivly the injectors will only ever flow 250 cc/minute with the standard pump.
That is only enough fuel for circa 277 bhp.
My car made 320whp @6500rpm with 7psi on the factory pump...and it wasn't running right during that pull. I have been running 10psi on the factory pump since with no lean issues as well. Above that, it won't stay rich.
Have an inline going in as we speak though for more though
Yeah it is a custom intake manifold, I thought about running it over that way but I liked the look of this better. Trust me though that extra tubing going around the engine does not effect how fast the boost kicks in lol It would have been more efficient to go to the other side though for sure
