300rwkw = gt30 + 1jz + boost = Done like a dinner

Nice result

Is it just me or does boost (and power) look to come on wayyy better in the top graph!

Nah, not just you...

Why tho? Was power FC controlling boost in initial run Jampac? Why'd you use the Blitz unit?

[chris davey]

I think it would be the difference in dyno operators. Many who do autos would not boot until about 4500rpm or so so that it doesn't kickdown even though Ben's won't do that.

Made boost come on later on the dyno as it was showing signs of heatsoak when bring boost on early. It was very close to 300rwkw bring boost on normally, due to the heatsoak you get. It shows I really need even higher octane fuel. Some octane booster would take it over 300rwkw when bringing boost on early.

Sorry for the dig, but can i ask what manifold you were using and also what A/R is on the 3076's exhaust housing?

Thanks.

[Dieseltrain]

0.86 rear housing but not sure about his manifold dude.

[jampac]

0.82 a/r It's a manifold I brought a while ago from a user off soarercentral. Was never fitted, before i fit it. Seems to work well. I think it was made in china.

[Xistant]

jampac what size injectors are you using/.

[jampac]

injectors are 650cc

[Xistant]

nice what % cycle were they running @ on your 300kw run

[Mazman]

seems laggy to me for a small turbo!

[jampac]

The dyno graphs boost curve was done like that so it made a touch more peak power.



That's the actual boost curve on the street in 3rd gear. It would have to be responsive for me to run in the 1.5x 60ft range without nitrous.

[jampac]

nice what % cycle were they running @ on your 300kw run

Somewhere between 70-75%

update?...

[jampac]

I'm currently getting my 1jz soarer tuned with big sticks (they are crower sticks about the same specs as HKS 264's). Currently is making around 250rwkw on 13psi which is up about 20-25rwkw on the same boost without sticks. The cross over point is around 4000rpm, and they rev all the way to 7000rpm. This figure is only on 98 ron fuel at the moment, so long way to go before i'll see what they'll make.
