Okay I read and read and read again and reasearched and read..so I know I wasn't just seeing things...This Chevy Cavalier

gallery_major08.jpg

makes 700hp and they out of 2.2 Liters...that's 5+ hp per cubic inch...does this not amaze anyone but me??? Its okay to see a 500 Cube nitro-methang blowen Rat motor pushing out 3,000hp but at little bitty tiny insy Ecotec pushing 700hp!!!

 

Here read about it:

GM Talks Horsepower

i think Lingenfelter has a 1000+ hp Cavalier. pretty sure thats what he cracked in too. too bad its still fwd.. can you say.... torque steer.

 

but i'm sure in a drag only car they have stuff to help keep it in a straight line.

Guys, I realize this is ancient history, but this bout w/ small displacement/4 cylinder and big power is not GM's first attempt (this ecotec is pretty solid, BTW for what it is).   :lol:

 

In 1987/88 (yes probably about the time paco was in diapers  :cheers:  Just yanking your chain paco!! ), GM had 2 versions of a Quad4 (2.3 L, 4 cylinder, 4 valves per cylinder), for use in the Olds Aerotech experimental/concept car.  

 

One had a 700 hp single turbo, and one had 1100 HP twin turbo.  My understanding is that they were running 25 psi, which is pretty high.  I recall, at the time, Mercedes was trying to get similar hp/Liter, but had to run turbos to 100 psi!!  They were blowing engines up right and left.  Afterall, what is pressure, but *resistance* to flow - GM's approach was less resistance means lower pressure.

 

I heard a video/audio of the twin turbo Aerotech, and believe me, it sounded like a 4 cylinder on steroids!!  :flag:

 

GM had lots of plans for the Aerotech and that twin turbo, but it tore up something like 2 trannys, so they never got to attempt several records they had in mind - a flying mile comes to mind.  

 

BTW, that original Quad4 was not the timid, bland, tinny, lobotimized and wimpy 2.4L that Olds and Pontiac offer as base in the Alero and Grand Am.

    • I would argue that GMPartsDirect has that info wrong.    The service manual for R+R the lower arm and for adjusting camber/caster, none of the steps say to discard and replace the nut or the bolt.    The only part that gets discarded is the plastic cam adjustment retainer that is in the eccentric from the factory.     The LCA nut torque spec is: First Pass: 180 Y (133 lb ft) Final Pass: 90 –105 Degrees    
    • The filtering to wear relationship goes like this:      'Relative Engine Life "Factor" new divided by the factor old. So 8/3= 2.67. That result is the multiplier thus if a motor had an effective life of 100K using a filter with a 45 micron rating at a Beta ratio of 75 then a filter with a micron rating of 10 at a Beta of 75 would improve expected engine life to 267,000 miles.    Wear metals are an indirect indicator. Less is better and the motor lives longer but there isn't a multiplier like there is for filtration so well documented. Most of that has to do with the sensitivity of the wear metals tests themselves. They read a 'slice' of the spectrum but not the absolute values for the entire spectrum. So a general indicator that is used WITH the results of other tests. Two others considered in this post. Trending is very important.    There is also the influence of corrosive wear which may be seen in the wear metals but separate from load based or viscosity mitigated indication. It's a small graph but the gray line is wear vs the TBN/TAN crossover. Not as useful as it used to be as there are now new chemistries for acid remediation that don't show up in standard UAO testing. They will catch up or be found liars. Only two possible outcomes, eh?             
    • One thing that comes up over and over is that the torque converters are the weak link. Many of the failed transmissions have the same thing in common. The torque converter grenades and then metal torque converter shards end up destroying the transmission. One of the best things you can do is if your transmission is still fully functional, change out to one of the aftermarket billet torque converters. There are several good choices mentioned in different threads here to make your choice. After that, then you can decide about trans tuning. My trans failed at around 95,000 miles. It got replaced under the GM protection plan. The remanufactured trans comes with a 100,000 mile /3 year warranty. I still have just under 1 year left. So far, so good. As long as it's still working good next year, an aftermarket torque converter is going to get installed early spring. If the trans and OEM torque converter fail by then, I will get it replaced under warranty and immediately have an aftermarket torque converter installed. A warranty replacement trans of a replacement trans will no longer have the warranty so I will bulletproof it from the get go.
    • You got'a be cooking right now. Just looked at the weather map. Yuck!    We are right back to $4 today.    
    • Pushing $4.00 a gallon in most places, still $3.75 in town but it's going to spike tomorrow for sure.   Diesel back up to $4.60-5.00.
