Some feed back for TRD Supercharger for 3.3L V6

[DrakkkarDarkbladE]

The Eaton M62 or M90 won't work. They are made for the GM 3800 Series II and III engines. I know because before this car I had a buick regal.

It would be way much easier to go with a turbo. Maybe wait another year or so for the new turbo technology to come out. Acura is currently using it. It's a continuosly variable turbo, spools up in the low and high rpms. Check out the Acura RDX.

Yeah I knew that they were use to be on the 3.8L of the Pontiac Grand Prix GTP (Supercharged) and Regal GS...but from the site

The Eaton Supercharger Model 62 is designed for 2.5L to 4.0L passenger car and light truck engines, but may also be suitable for other engine sizes, depending on total system performance requirements

The Eaton Supercharger Model 90 is designed for 3.0L to 5.0L passenger car and light truck engines, but may also be suitable for other engine sizes, depending on total system performance requirements.

I don't know if it's my poor english skills....but 3.3L seems to be between
2.5L-4.0L (M62) and between 3.0L-5.0L (M90). My main purpose is the low numbers on their graph...seems to not boost on a big time. Maybe their test was with a big pulley or I don't know how they measure the power but it'S like 25hp (M62) and 29 hp (M90) there most be something that I forgot to calculate !!?

Read that...the 3.0L TRD Supercharger was made from the M62.

...The big stick here is the supercharger. It's the ubiquitous Eaton Roots-type blower used atop production engines ranging from the Mercedes SLK230's 2.3-liter four through the Buick Park Avenue Ultra's 3.8-liter V-6 and the Ford SVT Lightning's 5.4-liter V-8. TRD uses the 62-cubic-inch version of the Eaton (the same unit used on early supercharged Buick V-6s) in the system it co-developed with Magnuson Products of Ventura, California, for the 3.0-liter Toyota V-6. The blower is driven by an extension of the existing accessory drive belt at two times engine speed to produce a peak 4.5 pounds of boost. TRD adds electronic boost control to modulate boost levels between shifts and to avoid detonation as the engine approaches its rev limiter.

With its own special intake manifold and with the Eaton between the engine and fire wall, this is an elegant installation. According to TRD, the blower gives the stock Toyota a 23.5 percent power increase, which works out to 47 more horses and 28 more pound-feet of peak torque over the unaltered V-6's 200 hp and 214 pound-feet....

If I apply the same boost percent 0.235 * 225 = 53 so around 278-280 hp
with the CP-e MAFci system I have now 242 hp (dynoed !!!) We would be near 300 hp (278 +15 from CP-e MAFci) and still miss headers setup !!! Stock headers are so retrictive with the U turn shape...just look under the engine you'll see what I mean !!

Let's make it happens...someday !!!

The turn isn't the worst part. You have to change directions somehow. The real bad part of our headers is where 2 pipes get merge into one of the same size. I think Brian posted a design graphic of a similar choke point on another model.

I don't know about anyone else here, but I can't help but get a little excited about our Canadian friend's findings... even if it's just speculation right now...

[Sebas007]

Yeah...let speculate...the jackpot of the lottery 6/49 (biggest in Canada) is about 42 000 000.00 CAD so around 37 000 000.00 USD it would help me to make it happens !

Seriously, it's SO easy to say that it won't work...I stay realist but motivated to make my own way to make things change.

BTW, the ratio cubic inch and liter is around 61. So the M62 is an 1L supercharger and the M90 an 1.5L supercharger.

I will take time later to right to different person of those company to know more about our 3.3L boost limitation. Maybe there is not more limitation than the 3.0L....maybe there is serious reason why it's more diffcult to do so. I still think that it's a question of marketing and selling.

Thanks down2thec to share it !
