Possible 190 HP 3.0?
I RR'ed my 3.0, ported, polished heads, oversize valves, headers, Downey x-over, 2 1/4" Exh, os injectors...! Engine parts from www. toyota performance.com
Does anyone think that's w/these mods it's possible? I also used CAM2 racing fuel! I got 190 on the DYNO!
When I get my results together, I'm going to post them, until then, is it possible that I gained 30 - 40 HP w/these mods? The boys at 4x4wire say no!

I wonder how much it has to do with using the racing fuel?....

I think it is possible. It's a huge gain but I've had cars and bikes dynoed and they results are usually fairly accurate. There is some error potential due to temperature and humidity but I would say that would be less than +/- 2%. The best way to find out is re-run the test. I'll be interested to see the results. I know I'd love to have 190 HP in my 4Runner.

1. Did you mess with the AFM or is it stock?
2. How much oversize are the valves?
3. Stock cam?
4. Stock compression ratio?
5. What size injectors?
6. What sort of mpg are you getting now?
7. Regular or premium?
8. How much did you bore it out, if any?
9. Any ECU recalibration? I noticed different A/F ratios on the runs. I assume that's air/fuel ratios.
As far as HP and torque...look at what the 3.0 Supras are turning out. I say yes it's possible, even probable. Just need to spend some money to get it. Personally, I would have dyno'd it using the same gas you run daily to tell you what your real-world HP and torque are. But on the other hand, the racing fuel probably wouldn't buy you any gains unless you're running extreme compression ratios.
Good job...It's nice to see a practical alternative to swapping.

Answers to all your questions in order:
1. Yes, I richened the AFM 1 step & that is all
2. I have no idea! I gave them to the machine shop $ said: "Do what you have to do to get me more power, he installed OS valves, ported, polished....! $600
3. Stock CAM
4.9:1
5. www.northwestoffroad.com -$419.95
6. 21-24mpg
7. 93 octane only $2.05 a GAL.
8. no, tweeking the AFM
This isn't very impressive results, but That's all she'll put out!
No lying that's as good as the 3.0 gets w/o putting A $1000 more into her!
Now I know you aren't impressed, but it's a 3.slo!!! :pat:

Now, I don't want to get you guys down... but that doesn't mean too much. If you talk to guys that dyno their cars often and are always upgrading, they will tell you that a single session of dynoing means absolutely nothing. Each dynamometer will give you different results. The only accurate way to measure horsepower gains is to do a dyno session before and after the modifications, and they should all be run on the same dyno. You might go to another dyno down the street and it may read that you have 200hp. Does that mean that you have 200hp? No, it means that there is a difference in the calibration of the machines. In that same manner, Toyota's dyno is going to read different(both for the obvious reason of crank vs RW) and the fact that they are calibrated differently. While you may actually have gotten the hp up to 190... I'd have to say that your dyno run doesn't mean much on it's own.

The low end on a 3.0 is awesome! Some will disagree, others will agree!

70-75 mph is about it on the Hwy,( I need new gears!) She starts to wind out, I have never taken her above 3500 rpm's when driving, ever! It puts to much stress on the engine, a 22re is a different story!
