ugh yeah it is.

10's! Way to go, faster than a Hellcat.

miata2fast 01-19-2018 04:43 PM

Could you tell us about the launch? How much rpm can you get foot braking at the start? Any significant wheel spin?

mx5psi 01-19-2018 05:24 PM

Im just doing a burnout in second gear and i brake boost it till i feel the front pushing no real wheel spin it scuffed a few times but all up it hooks and launches there were people video-ing at the track so hopefully there may be videos coming

miata2fast 01-19-2018 06:42 PM

With your mph, the most optimal 60' times would be in the 1.4 range, but it takes pretty much a perfect setup. So I say you are doing pretty good. This is when a transmission brake would really help you.

I have my doubts anyone has gone as fast as you with the turbo size you are using. That right there is bad ass.

mx5psi 01-20-2018 02:37 AM

Id hate to think of what i need to change to get a 1.4 maybe i strip weight. Im not really sure at the moment

Health check
 
i just comp tested all cylinders within all within 5 psi and check my catch can after 6 or 7 runs and a big drive home on the freeway about 3 or 4 cold starts it only had 120mm 20mm of that looks to be water which i think is good.

my only issue and concern is the comp tester shows

Warm
CYL 1 - 100psi
CYL 2 - 95 psi
CYL 3 - 95 psi
Cyl 4 - 100 psi

Cold

CYL 1 - 95 psi
CYL 2 - 90 psi
CYL 3 - 90 psi
CYL 4 - 95 psi

it runs way too well to be broken it doesn't smoke bugger all blowby considering the boost its on so i am going to get another compression tester from work and check it is turning over very slow maybe thats it or maybe the cams (over lap i dont know ) that are throwing my readings out. it makes the same power so i am only a little worried.

mx5psi 01-21-2018 08:39 AM

worked it out
 
its 12:36am here in aus but it was bugging me so i went and had another look in the shed and relised the Snap-on comp tester i borrowed had a very strong one way valve ( the wrong one ) so i replaced it with one of the spares from the box and checked one cylinder and boom 165psi.

so the fact that there all consistant i wont bother checking the rest.

18psi 01-21-2018 12:22 PM

I was just about to suggest that its likely a low reading tester.
Consistency = key

patsmx5 01-21-2018 04:34 PM

Well that's fast. Nice! What turbo are you running again?
