routed the vac line so it goes through the heatsheild and mounted my boost solenoid (ecu has boost control in it). should help with the vac line from perishing from heat.

Car is still boosting high for some reason, but now makes 351kw @20psi. If I drop it back to 18psi it sat at 345kw. But it is really happy making that power atm.

Also dropped the rev's back to 6500, and the afr's are 11 to 1 for a bit of safety

Dont mind the dip from 4700 to 6000, got a manifold leak on the last three runs from Not tight enough and cooling down over lunch.

Rocked up to a speed off the streets day at wakie yesterday for a bit of a test day, got 8 laps in and broke a stub axle sad.gif

Other than that the car felt excellent. The extra power and reduced weight has really change the car. Going to take a few proper laps to get used to, but the car will take any opportunity to slap me in the face if I don’t concentrate
I did manage a 1.10.10 in the lap before the axle went, which is about 1 second quicker than what i normally do in the 1st session. So i take that as a good indication im on the right track (no pun intended tongue.gif )

Also, even though tyre were cold, grip feels better too. Definitely more front and rear, was less understeery with the modified splitter. Will have to wait until I get a proper run to judge the rear.

Im now trying to find a couple of sets of 4 stud stub axles, so if you have a spare that you want to set cheaply please PM me.
As much as i would like to, im not going to order the billet ones from the states as they will take too long to get made and sent.

ive got two sets lined up already, hopefully i'll be able to get a set in this weekend.

Only thing that worries me is why it broke.

was it because of the extra power and grip (even though not much) or was it just because it was 27 years old and stressed from the last couple of years of track work, or a combination of the two?

either way i dont see much point of pouring much more money into the rear end as it is, and so after wtac i will be putting my stag rear end in.

lowered the skirts to match the front. Not the prettiest but should help stop some air getting sucked under the car. (front bar/splitter just sitting there atm)
Once again, please excuse the mess.
got some new stickers ready to go on too.

Had a good day at the track today smiley.gif shake down and test one set of the advans

New PB 1:06.31, beating my old pb by 1.1sec yeah baby!

Both the car and I felt really good, and the grip from the advans is just insane.
