[34GeeTeeTee]

I challenge you to a lag comp next month, Dave

[NYTSKY]

71 or 76?

[DVS JEZ]

Very first pull on the dyno, well once i changed to a 7 bar map sensor. I used 16psi springs in my twin scroll manifold. But for some reason 22 is my low boost. Its a major job to get the wastegates off as i have plumbed them in and very little room to work around.

On this run i backed off at 6400rpm

Overlay shows my previous best with -7 copy twins.

Both on E72, both have same tyres etc etc. the e72 in the tank atm is 6 months old

How about some rpm scale love there Jez instead of road speed?

All looks promising so far - I bet you're happy!

Gotta be happy with that jez

I can try for u stevo but its only roller speed and i can input what rpm at a certain Speed if that makes sense. I mainly use it as a reference. Worst part is it doesnt save each time the dyno is on so i cant do comparo's on different days with rpm.

Very. Cant wait to push some timing into it. Think i might stop at 420ish kw. As stock engine and cams

[SiR_RB]

Holy crapp

Goodwork buddy can't wait to c ur final results then out at WSID for some 1/4mile runs lol

[SiR_RB]

Also good to see proven results that stock rb26

Head/cams can make huge power

[SimonR32]

Will be interesting to see where it ends up after tune is finished!

Hurry up Jez

[Deano 1]

Farout, anyone want to buy a set of -5s? Lol

[KURTIS34]

You know you want to upgrade deano

Very impressive first pull

Damn you Jez beat me with out even trying

Yeah that makes sense, fair enough.

When's more tuning going to happen?

Putting fresh fuel in for that?

[N1GTR]

Would be great for someone to do back to back testing on a range of these things. Eg 5557, 6262, 6466 etc all on the same engine, same dyno

[GTR_JOEY]

What twin scroll manifold and gate/s are you using for the precision Jez?

I think I put a link in here a while back from some guys who did just that, albeit on a 3.4L jz

[DVS JEZ]

6 boost manifold twin tial 38mm gates. Custom dump and plumb back piping.

Stevo hoping to get the rest tuned on e70 sunday. See what boost i need for 420kw. Then wsid for a 1/4 mile run to see if she holds together

[SiR_RB]

Soo surprised it comes on at almost the same time as -7 size turbos, makes twin turbos look like junk

[DVS JEZ]

I will overlay it with urs and Andrews when i go to shop tomorrow. Curious to see
