Time attack did.... unofficially 320whp off nitrous, 400whp with a 100 shot (higher comp pistons would get me there).

Other than that, I have the highest power numbers with an H62. Back in the day, a member on the redline forums made 270whp with a 2.9, 42's and exhaust with an H62.

I'm not into all out power numbers. I built my car to follow the buildbook and time attack engine specs, and I've hit my mark. A 50 shot and some other tweaks will be made over the next few years, but thats about it.

The power delivery of my car is very strong, and it pulls hard through the whole band, actually at any rpm it will put ya back in the seat nice.

Good enough for me

 

Depends on person. No 300hp cobalt will put me back in the seat

Decent numbers though

 

lol....ok.

 

Just the first time I heard someone say they get thrown back in a seat in a 300hp cobalt lol

 

Didn't Brian unofficially make somewhere in the ball park of 320whp on the h62?

 

Never said throw. I said it will put you into the seat. When you punch it, it will. Not saying it will hold you there throughout the pull like "omg gawd I haz mad powerz bro".

It was a way of expressing the car runs strong. Doesnt need to be taken so literally.

For reference, I have been in much more powerful cars than my little 300hp Cobalt. So I do know what actually being "thrown" back in the seat is.

06Black?

Not sure, he might have. Never saw the graph.

I forgot he had one back in the day.

 

That's why I said unofficially...

That crew didn't like to publish graphs

 

Where are the rest of the H62?

 

Missing/destroyed.... There were a total of 7 at one time (not including Time Attack).

There is one other I know of that may still exist. He is a member on here, but hasnt made a post in years.

Last time I spoke with him, he still had it installed on his car.

No they def did not.

So I'm "officially" the highest powered H62 car, lol.

Me, myself, & I!!

 

Woooo

 

I did.

 

Yeah you did...one of the few

I never even saw Shaun's; and we used to hang out regularly; though knowing him he probably lost the sheet

 

Yep some pretty nice numbers

 

Agreed! Area def provided us with juicy info on his setups.

Thank ya!

 

Only 7 made!!!??? Good job man, I always thought with my GMStg2 honed mani and hahn exhaust I made good power but wondered why I was making peak power a little higher in the powerband, i chalked it up to the injectors running lean but I guess that wasnt the case...

So I've been out of the game for a while and missed the whole 1.6 lysholm SC unveiling. Guess these were a one time thing? If so how many of these rareties were made?

 

Thanks!

Only a few 1.6 lysholm kits were made as well. Not sure on the exact number.

 

2 Complete Lysholm 1.6 kits were made; sold to blackmagic and Jittjoey
As well as 1 Lysholm 2300 kit

 

I think that the H62 would have a little less power output than a TVS on the same size pulley. It's been proven that the TVS on the original pulley makes 280 WHP on a completely stock LSJ and if you were to pulley down to a 3.0" pulley it might gain enough power to make 290 WHP.

Now this is just an assumption but because of the displacement increase on the TVS; same pulley size; I think that it would make about 15-20 WHP less than a TVS. Could be more or could be less.

 

Point of all of this??

It's obvious the Harrop would make more power than the H62. No need to compare.

Regardless, I still make more power than some TVS setups out there. Well, actually my blower is a TVS as well, just a 3 lobe version....

Not only is it a TVS, it was an early prototype for the 6th gen rotors.

 

Is the h62 the .9l tvs prototype they are talking about in this article from the tvs1900 thread

Staged...you should go turbo


teehee

 

Nope. The H62 is a 1L blower.

It is unique because it still has 3-lobe rotors but they are twisted double the angle of the M62 rotors.

Hey man.... you should be banned for a week.

teehee

 

I wasn't knocking the H62 but rather comparing for those that didn't know the output of a TVS versus your H62. That's what the point of that was.

If all Eaton has to do is twist the lobes more then why wouldn't they make rotor replacements? Cost aside...

 

I didnt take as knocking on the H62. If you want to make a comparrison, the H62 was tested to make about 20whp more than the M62 at any given pulley size.

They were going to make a rotor replacement. It was rumored as a GMS4 kit. This was way way back in the day though.

You really cant just swap my rotors into an M62, because the outlet port on the M62 would not match the twist of the 120 degree H62 rotors. Porting would need to be done.

Most likely a good reason why GM scrapped any plans of such a thing.

I asked Eaton back in 2010 if they could make me H62 rotors, and their answer was the cost wouldnt be worth it since it is not a production blower.

 

Have you ever had the H 62 apart to take a look at how good of condition the rotors are in?
