i have a sc300 with a 1jz-gte twin turbo motor in it. i did a single turbo swap and i was wondering how my dyno run looked. is it to lean/rich. should i take more off.
the guy said that the dyno dynamics dyno reads low compared to others.he said around 10% lower. im going on a dyno jet next weekend
my car is a 5spd
the tune was done with a safc and a stock soarer ecu i think this is at 23psi
no detonation
my setup is
gt35r turbo, tial wastegate, stainless mani, 3in dp, 3in exh staright pipe no cats, greddy bov, titan cam gears(set at 0), greddy boost controller, greddy bcc,
550cc injectors, walbro pump.

would messing with my cam gears even benefit that much where i would need to mess with them? alot of people only say 7-10 hp?

Congrats on going single. Post some pics of the engine bay when you get a chance if it's 10% lower then you should be at 467.8 HP@23 psi. I will let someone else chime in on the A/F and safc settings I'm still learning about that stuff.

we haven't done anything with timing. cam gears are set at 0. only tuned on the safc.. what would you like to know about the setup?

full boost at 4200rpm i didn't think that was to bad 24psi

Nice numbers. What kind of transmission are you running?

Numbers look good as well as your a/f. What type of gas were you running when you dynoed?

got_trd

Hes still using the W58...

99navette- i take it you figured out the sputtering issue? what was it?

Psionic

Please tell me you still get good gas mileage... That would completly seal the deal for me going 1jz.

I am interested to see how long the W58 will go with that amount of power. I am very close to reaching that 400+ rwhp level but not sure yet because of the tranny.

BiZ

At 23/24PSI 390 rwhp seems a little low. Maybe it is the difference in the dyno. If you ever get to run it at the track your MPH will give you a more accurate measurement of how much HP the car is making.

What kind of power was it making with the stock twins?

You can get good gas mileage as long as you don't boost but then again that's not easy with these cars.........

what fuel system are you running??? 550's, 650's?

it looks real rich to me... I would try tuning for 11.0-11.5 on pump gas... you are close, but it looks like at high rpm you are going way rich...

BiZ

The dyno reading 10% lower could be very true. But by looking at that graph posted up top the 425 reading was a spike at the end. I have seen that happen from time to time on dynos. It can be misleading. I wasn't trying to be negative, I apologize if my comment came off that way.

very good point... I would be willing to bet if the car could be leaned out a little more, especially on the top end, that it would easily make a "clean" 425 or maybe more wheel hp... that 425 reading was when the car finally leaned out a little...

i was running 93 octane gas on the dyno. i have 550cc injectors. ya the guys who tuned it weren't 1jz experts but im going to get it dynoed again. as far as gas mileage its good as long as you don't hit boost alot.

the missing was from my greddy bcc no being tuned right.. i messed with that and then drove it again and it ran perfect. pulss hard as can be

HEY BIZ? where did you get 390rwhp??? im at 425rwhp by their dyno but everyone says this dyno reads 10% lower then other dynos. so im really around 470rwhp. and also thats being tuned with a safc and having the cam gears set at 0 still..

i have a w58 tranny and it holds up fine.. i just don't slame it into gears. go into it nice and slow and still walk everybody lol
