Boosted but slower than stock!

[Dawgz]

what was the change?

[Astro]

Did you guys ever see change #1 to the SC install book? The setup changed..

Yes, if you're talking about the supplemental that came with the EBC (as I stated before). But, when I hook it up that way my car just bogs out when I step on it. Besides, I don't have the EBC hooked up.

what supplemental?


Is it okay that im running the EBC along with this "boost on demand" mod?

[Astro]

There was a supplemental given in '02 along with the install manuals for the EBC, and it showed to run the hoses the way you had it setup. Except for the 3 way connector you added.

A member here, Greg, told me about doing it. He has an auto Camry (but recently he did a manual swap). I think he had it setup like that for awhile w/o any problems. Give it a try and see if it makes a difference, you can always go back.

i tried it the way vampire told me, basically how u have it as well, and i do feel a better kick when i get on the gas.

[Dawgz]

Ok so today i went and got the car dynoed and tuned (safcII)


the first run withought any tune, i got 166whp and 177 torque.


after some tuning and more runs, we got 174whp and 185 torque.


the guys there said that my exhaust is bottlenecking my performance, the pre cat and the old cat i have in there.

he suggested getting headers and a better y-pipe, and also replacing the cat with a high flow cat or even a test pipe.



anyone got any reccomendations?


ill put the dyno graph up after i have it scanned.

[that1mexguy]

Something doesn't sound right, and unfortunately i have no recommendations. I would've thought even with a 4psi you would go over 200whp. We pretty much have the same set up, except for the pulley and I don't see you having the fuel pump, Supra fuel injectors and MAF (not sure if that would make that much of a difference). Have you upgraded your clutch? I only ask this cause it was my understanding that even at 4psi the OEM clutch could not handle the S/C (I know mine didn't so I had to upgrade before getting it tuned), but if your clutch is OEM and handling your 4psi, then it's not producing the right power... again, this is simply my opinion but I feel there is something missing here, unfortunately I am clueless at this point.

[Akfahad]

what was the ultimate A/F ratio the guy tuned the car to?

I have no other recommendations either to tell you the truth. As already said, you should be over 200whp at the stock boost. Although, it could also be the dynojet machine. Their not all the same, they read differently, as was my case, except it said I pulled an ensanely amount of HP when I know that's not the case. It could be the factor. But...the tuner is right, adding Dats Y-pipe opened up the air passages sooo much more. Unfortunately, he's sold them all and not making any more. Unless you come across someone wanting to sell theirs or going the JPP way or getting a custom Y-pipe done. I think you'll see more rewards doing the Y-pipe, but of course, if you can afford both headers and Y pipe, do it.

[99V6solaraSE]

so even without the exhaust and y pipe and all that, he should be hitting 200whp at least?

[CamryOnBronze]

I would think so... his numbers are what a stock v6 solara has at the wheels basically arent they?

something is messed up bro...

[Eye8Pussies]

he has an auto, doesn't he? and those are dismal numbers....

the first untuned run would be basically the same power as an auto 1mzfe w/ bolt-ons (a little bit high on the whp side though)

and the second tuned numbers would put him even with a stock 5-speed 1mz.


what were the A/F's like? did they hook up the knock sensor alarm? The only thing that can really hold back that much power would be retarded timing if you ask me. Or an engine that's about to die.



And a stock auto 1mzfe that's running 4psi is NOT guaranteed to put down over 200whp. That would take bolt-ons plus some tuning usually.

Repeat after me:

Step1. Remove and inspect spark plugs

Step2. Do compression test on each cylinder.

Step3. Install next temperature range colder plugs and gap them wee bit smaller than factory.

Step4. Verify proper ignition timing.

Step5. Check vacuum hoses & intake manifold gasket for leaks while engine is running and giving it gas by yanking on throttle linkage in engine compartment.

Step6. Install SAFC and go for dyno tune. Just going for a dyno tune without completing at minimal the previous steps is a waste of your $.

Do not start at step6.

whats better than NGK Iridium IX? thats what i have in there rite now

[CamryOnBronze]

there are different steps of plugs, it would still be the same brand I assume, just a different temperature

[ProRally Codriver]

Iridium plugs are great, but did you get the proper heat range? Boosted cars run with colder plugs than normally aspirated cars. 4 lbs boost ain't nothing though. Don't know if I'd invest in TRD supercharger for just 4 lbs and no simple method to include intercooler.

So what were the results of pulling plugs and inspecting? This rules out many ignition and fuel problems you may be experiencing on just a single (i.e. faulty fuel injector or poorly connected ignition wire) or couple (i.e. crossed ignition wires) cylinders.

What were the results of compression test? All normal, all low, 1 or more low? Easy cheap/free trouble shooting. Did both to one of my peforance cars today and discovered something and fixed it.
