I'm swapping the BP-4w cams, and to do so I had to remove the head... But! the major lift makes the lobes interfere with the lifter seat, nothing a dremel would not solve
Also, the 6758 is finally arrived, beautiful piece of art

Screw you differential, you've stayed together now over a month, can't have that!

That compressor wheel is purty.

Carbon residues, lots of
The car was knocking no matter the ignition advance, even at 10 degrees at 190kpa was knocking, so this was the first reason I pulled the head, but the carbon was simplu causing auto ignition, so tomorrow the machjne shop would investigate upon the head to solve the oil leak problem
luckely the pistons are in great shape, I opened before do some damage

Oil burning can create detonation. It has a lower octane than gasoline.

News: I disassembled the head, and noticed that all the intake and exhaust valves are wet... Oil I mean







also, swapping the BP-4W cams in the BP-05 head I noticed a problem: due to the major lift of the intake cam I had to trim a little bit of material near the lifter seat

before:



after:



Very close btw




and this is a shot of the intake cams: left is BP-05 and right is BP-4W



1mm lore lift and much wider opening

Oil from valve stems explains the detonation.

I don't know if I told you thanks for the help with the 3.63 gears. I got to 150mph (241kph) at Daytona Speedway.

Glad to hear that! Sadly it's the maximum speed at 7.200rpm with 6 spd and 3.636
If anyone is interested I can have 3.9 gears in one or two weeks

Btw
cleaned the pistons, they look like new, even the supertech logo is still there







The head is at the machine shop to set the backlash and clean/inspect everything, next week should be done.

Last but not least








First of all I want to run the gt2560 again to see the gains with the bp-4w cams and solid lifters, I did a virtualdyno log the day I unbolted the head, just to have a before-after log with the same tune

Oh, some weeks ago I also received the 11.75" trackspeed bb kit, but it didn't fit with my wheels... I had to order a set of axe ex8 8x15 et30 that fits nicely the bb kit

150mph is not the top speed of the car with the 3.63 and 6speed, I just ran out of track and had to brake for the turn.


Pics of wheels? I'm not familiar with the name.

That's impressive! which tyres are you using? Redline?
I'm thinking to change my oil pump gears for the billet ones, just for be safe... until then I'm running the stock 7200 limiter

This is the axe rim, wich fits perfectly the 11.75 trackspeed rotors: 15x8 et30











I'm waiting a set of toyo proxes t1-r (hope they last at least 2000 km this time) 215/45 R15 to test it

Pics of the head work:

safety first





three angle valve seat job





still wet of oil









obx dual feed rail



trying to fit the lpg nozzles with the massive rail



done





voilàt



new spark plugs and…



same spark and ve table, notice the lean mixture past 6200rpm, that's a good thing, it means the engine breaths better and "wants" more gasoline



total gain: around 7.5%, 20whp with my particular configuration

I was using Hoosier slicks in 205/50 15. The redline is 7200 or 7400 but I can't remember which.

Finally I managed to install the TSE bb kit (VERY big brake), I confirm the fitment on the axe ex8 15x8 et30, due to frequent overheating problem with stock rotors and calipers:


New tyres (the T1-r are crap… trust me, don't buy them if you wanna do some trackday)



215 compared to the 195 on stock rims









same circumference: 195/50 vs 215/45




safety wire, all bolts torqued to 25Nm:



installed





done









even if I cleaned the rotors, they become blue after the break-in






Another thing: my current oil catch can setup have a problem, if I run HARD the breathe filter become wet of oil, even if the can is empty, and because of this it squirts oil everywhere (very dangerous if the manifold is glowing hot), so I decided to go from a dual 10mm ID inlet and single 10mm ID breather to a dual 10AN inlet and a dual 35mm breather filter, using the beefier joints I could find.

Current state of the can:



the diy catch can kit (well, part of, the can itself will be an iron one):
