hey everone i just got my 91 mr2 turbo on the dyno for the 1st time........... completely stock except a little bit of exhaust work.........what is the expected out put atw? i got 153.9rwhp or 114.6kw this was on a hot day and they didnt use the big fan ndoes that make a difference?
That all does really make a big difference... also whenever you do a dyno run u wanna make sure that they use the wideband 02 sensor. The horsepower you should be expecting to make at the wheels should be (factory) 200 hp minus 20 % for drivetrain loss. then consider the exhaust which might give u a little or more, depending on if u have rid urself of that dredded B-Pipe which is the second Catalytic converter basically. So your run should have been 160hp ATW plus your slight gain from the exhaust. A hot day.... Some needed maintainance ( not that u haven't done it all) no fan, a cold day, and all this takes into effect... A tune up properly done, (cap ,rotor, spark plugs, oil change, coolant change, and new wires) will be a big one if u haven't done so. This should put you back up to where u need to be given everything in your car runs right. And that might be the 6 hp difference that u were looking for.... And then the exhause which if u didn't replace the B-Pipe u might only gain like 2-3 hp.Also Dyno runs usually come in sets of 3 runs for like 50-75 bucks
well standard it would run 160 hp at the wheels its done just over a 100k on the clock would age account for the loss of 4 hp and the really hot day and no fan?
Not from what I have heard... after all the fluids have been changed, new plugs wires, and cap rotor, and all that good stuff it should be pretty close... But I guess u can't complain about only 4 horses... however u did say that u had some exhaust work done right?
what type of dyno is really the most important question. also depending on how the tester had the ramp on the drum set, any boost leaks, quality of gas, alot of things could contribute, though the ambient temp and no fan are most likely the cause, i wouldn't lose sleep over your numbers.
sts alright i just put on a boost controller and boosted it up 2 psi what would do for affect................... damn that stock boost cut.........need a new ecu
Do you have a 3SGTE with an AFM/MAF?
If so, just cork the vac line to the map sensor and you will no longer have fuel cut.
The MAP sensor on the 2 gens is only used for fuel cut and to operate the stupid factory boost gauge.
IF ... IF, you have a 2nd generation 3SGTE that uses an AFM (air flow meter) to measure the incoming air, then you do not need the MAP (manifold pressure sensor) for fueling purposes.
If you have the AFM, it will be a big sensor between the turbo and the air filter.
It iwll have a big black set of wires going into wiring harness.
IF you have the AFM, you can plug the vacuum line that goes from the intake manifold to the MAP sensor. If you plug that line, your stock boost gauge (which is worthless) will stop working and you will no longer have fuel cut. It will not doing anything else.
If you have a Gen 3 engine, you CAN NOT do this.
If you need to locate the MAP sensor, it is on the trunk/engine firewall on the right side of the car. It is next to the diagnostic box. It is black and has a vac line running to it. Simply cork that line. Do NOT discoonect the sensor electrically.
That would be the Gen 2, so you should be fine o plug the MAP sensor.
Just keep in mind that plugging that in completely eliminates fuel cut, so you do not have that protection. Just be vigilant about watching your boost so you do ot go over 15 psi.
I hope (and assume) you have a quality boost gauge in your car that you can monitor boost with.
If you buy an HKS FCD (fuel cut defender) you can RAISE fuel cut to 17.7 psi and still have some protection.
I ran for 3+ years with just plugging the MAP, but I was always very careful about my boost.
If your engine is completely healthy (good compression, good leak down)
... and ...
If your ignition is fresh (wire/cap/rotor new within the last 2 years and fresh spark plugs)
... and ...
If you are using 93 octane (U.S. measurement, not sure what your octane rating equivalent is over therE)
... then you should be fine to boost up to 15 psi.
I would never, ever run over 15 psi with the CT26.
