Ah shit tom, dya remember that clown on fduk that tried selling one for about 300 quid and was adamant he'd get that money for it 😂 what a retard 😂
 
Looks good man!

Out of Interest, any reason you decided to buy pre-mix meth?
I just got a big barrel of 99% meth and mixed it with deionised water when I ran meth in my last car.
 
I don't bother running meth tbh, I'm running water for the cooling benefit and unless tuning for meth then i can't see the point.

Worthwhile for a drag car where your trying to get every drop of hp but for a street or trackday warrior water does the job imo.

Spot on, I used to run a JB4 with a fail safe box on the pump, with a backend flash I wrote off the back of a full methanol flash. Only benefits of a strong meth mix was the insane amount of octane I could then achieve out of pump gas.
 
I may well do a home mix for my next batch but I just bought it as it was easy for now.
 
I'm having some boost creep issues with the 8374 and have had to tune the car right down in the bottom/mid range in order for the boost to not spiral out of control. I have had the wastegate ported which made it just about manage to control the boost but at the expense of low down power. I was planning on upgrading to a link ecu anyway which combined with a 4 port solenoid will hopefully allow me to control the boost better and map the car properly down low. Failing that I will just get a ewg manifold and either weld the wastegate shut or replace the housing for a ewg version and run screamers or plumb them back in further down the exhaust.

fairly pleased with the peak figures as my goal was 450bhp and I made that at 1.16bar but it starts to creep again at about 7.5/7.8k so I'm not really revving it out any further for the time been.
 
Great figures!! 450 seems to be the magic number for this turbo.

Why does the tq for flat between 3k and 4.5k? This is just where it should be horsing on. Also the torque drops off at 6k, i would have expected this turbo to be well over 7k before it tails off.
 
Ah sorry i re read your post and saw you mentioned the boost was spiking. This will be why the torque flattens a little after the initial spool up. Still great figures and i expect your super pleased with how it goes now.

Yeah its very strange isn't it. The way this thing makes boost is insane lol. The first run he had to back out of it as was climbing like mad was at something daft like 1.3 bar by 3k and rising lol. On another run i was at 430hp by 5.5k lol. Going from what pip has told me, he has had to massively down tune it in a attempt to keep the boost undercontrol. Im only running a 7psi spring lol. Im kind of thinking im gonna have to go down the EWG route in the new year.

Yeah it's pretty ballistic above 5k lol.
 
Great figures mate! External WG time by the looks of it though. Must be entertaining to drive 👌🏻

Cheers bud. Yeah it is pretty relentless over 5k. I'm happy with peak numbers just want it all to come on earlier like the efrs are designed for although if the tuning for that results in even higher peak im not going to complain lol. I'm going to have another try with a decent 4 port solenoid and link ecu and if that doesnt do it time for screamer pipes :cool:

Link FTW

I have the link Extreme 👍🏻
 
Gave the car it's first clean in what's probably been a month. No where near perfect but it will be getting a proper polish and clean before hibernation. Need to clean up all the engine bay as grease and dirt is pretty bad on turrets etc. Over all though she cleans up ok for a 21yr old. There is a a couple of little marks here and there but I can live with that. This car is going to get tracked hard anyway.

I also had to spray the hanger and bolts on the RB exhaust black as I couldn't live with those chrome bolts, might of just been me but my eyes were always immediately drawn to them when at back of car. They are much less noticeable now and just sort of blend in with the tow ring.
