Garry,
re tracks/training

if you want to dream in technicolour..........Ron Fellows has a school just
outside Vagas. According to reports from many participants the school and
lodgings are just fabulous. GM pays for US buyers of the ZR-1 to attend the
first 2 days of the 3 day course. [ think its ~ $3000/ 3 days ?? ]

Tony,
welland

Spring Mountain..... if your going to do a course, thats the place to do it.

Good evening 4ryanr,

It is an exciting time in my life for sure. The decision to go with the mods, Manny patiently walking me through it, the dedication of his staff to fulfilling a customer's dream!

I've purchased a camera mount for the car and one for my helmet to be able to take some videos. I have to the video camera's next.

Since you are, like Colin, local to the area, you may be able to attend the reunion! At some point I will be coming down to get the car and maybe even before that depending on how my spring goes and the weather there. But I will be posting on the forum when my plans are in place as I want the chance to meet as many of you as I can.

My bank account would not survive a 2nd winter there so I don't expect this is something I'll be repeating in the near future!

It will be such an experience to be able to see as many of the member's cars as well. A dream come true for me..........

Cheers,

Garry

Sure would like to meet up with you and the rest of the crew when you do make it down here to pick up your new weapon:D appears that spring is near with weather in the mid teens today!!
 
Keep watch on your inbox and I'll let you know when he comes.

BTW I live on the west side of Galt on Harwood (off GrandRidge) and my twin brother lives in Hespeler on Calvin Ct. off Ellis Rd. and Adler.

Colin.

Thanks Colin I'm on Attwood 2 streets from Manny's . I happened to see a zr1 in a garage on granite hill rd this weekend not sure who this is or if he had just picked up this beauty its cyber grey metallic ,i believe as i only seen the rear ,maybe he has checked out this site :confused:
Not to be a stalker but a Vette owner are friends i like to have:D
 
Cool -- stop in sometime and tell him about us at CCF. Another member would be great and ZR-1 members are rare for sure.

He/She has to know some of us and seen some of our cars around town.

LOL, as he lives in your area, he's probably seen (or heard) you guys on occasion.......:D

Good evening Colin,

Perhaps it might seem high to some.

It was such a long time ago but maybe some of you other fellows with a more classic education would be able to understand. How about:

"in Manny credemus"

Cheers,

Garry

Sounds like you misinterpreted the intent of my question. It was just that, a question only, and not a criticism.

LOL, no worries Garry, I have mucho faith in Manny -- So much so that I've entrusted my car to him many times......:D

What I was quietly trying to do was query the difference in boost pressures between cars and their s/chargers. Some have about 8# others like yours 12#

Just trying to learn a little more in my travels.:D:D

how much boost depends on the way the engine was put together. what the compression ratio is, whether forged and billet internals have been used, if the block has been o ringed, cam, valve and port size, etc. etc. if an engine isn't breathing to it's full potential it'll need more boost in the higher rpm. supercharging increases the compression ratio ratio substantially, so running alot of boost would make using c16 race fuel mandatory. engine displacement also dictates the amount of boost. in case anyone doesn't know, boost is the amount of air pressure forced into the engine greater than the atmospheric pressure. natural atmospheric pressure is 14.7 psi, so with 12 lb of boost garry has a total of 26.7 psi. :coolgleam:
 
Garry's car has boost in more ways than one! Boost in the engine and a boost in speed! That car is going to be awe-sooooome! Or I should say, is awe-sooooome!
 
supercharging increases the compression ratio ratio substantially

well raises volumetric efficiency officially I think... and an engine being an air pump increasing the air through the pump makes more power... assuming a perfect world twice the air creates twice the original power... so Garry's 448 to 744 is 166% and 14.7 to 26.7 is 181% (makes sense because of loss to heat, turning the blower etc.)

Thanks Doug and DrJer -- I understand that and am learning more about the science of it here ---- looks like Garry's car can stand the higher number due to better/modified internals that will take the extra pressure. It makes sense.:D

Knowing how much pressure must include some trial and error lab testing long b4 any install for us lucky owners.

I'm sure a lot of thought goes into what pressure can safely be used on any particular build while factoring in a reasonable amount of safety -- LOL, One wouldn't want to ride around 'on the edge of blowing up' all the time.:rofl:

I'm sure Polar Jet will be very happy with 8# ..... and Garry will be fine with 12#.... I'd love a mod like this myself.;)

fuel dragsters and funny cars are running in the neighbourhood of 3 atmospheres. remember the old days before the kevlar blankets were mandated ? if things went south it was common to see a blower shoot 75 ft in the air with everyone trying to take cover when it returned to earth.
 
Colin Colin Colin,

It was NEVER taken as a criticism!! I would never know why 12 psi was chosen, just that Manny know his stuff and with the goal I had in mind that he would be able to suitably decide how much boost to use for power/relibility goals. Thus why at 8 psi it was fine with stock internals but when we went for more the pistons had to be upgraded so they could withstand the additional stresses.

If you're asking me about the proper leaf stage to apply a herbicide on canola at I'm your guy but when it comes to modding engines I'm not so good there. Thankfully I know who to turn to for that advice and as in the case my soul with the Almighty, so in Manny do I entrust my Z06.............

Good news weatherwise finally, a warming trend, not until Friday/Saturday when highs of +5 are currently forecast but it is on its way. -21 this morning but no wind and a beautiful blue sky at sunrise.

Cheers,

Garry

I do remember Doug -- I was in the stands at Indy many a time when engines let go and sprayed parts (and oil) all over the place.

My brother saw a blown top fuel engine fly out of its normal resting place and hit a camera man standing on a perch between the public fence and the track's finish line. While the cameraman was tracking what was left of the car, the engine that had 'bolted' came up beside/behind him, struck him full on, and killed him.:mad:
A freak accident but after that, no more press or anyone anywhere near the finish line.

That's back in days when rules and safety equipment was much less than what they are today and horsepower was probably half what it is today.

Also witnessed quite a few rails going thru the lights and no 'chute opening up. That's exiting too watching the driver go thru everything an into the cornfield at high speed.\

Do you remember the fuel atltered's? They were around for a few years but very dangerous and eventually banned. I can't count the number of times those totally lost it and crashed.........

I've been in the stands when bits and pieces fly into them too. No apparent injuries that I saw tho.

Yes the drag racers do boost pressures to phenomenal levels -- and then add something called nitro methane to the mix ...... No wonder they call 'em "ground pounders" -- the certainly do. Quite an experience for he novice.

Ahh the good old days.:D

fuel altereds ? you bet !!!

Did you guys set the red line to 6000 rpm? And/or is there concern of overspinning this blower?

(My math: 52000/(8.25/3.4*3.6)=5952 rpm)
