Ultimately, boost is a somewhat variable number that doesn't tell the whole story -- what really matters is cfm and cylinder pressure :tup:

Bring on the dynos!!! :yum:

Nicely put Jordo.:tiphat:

Err I should say, more cfm = more power...

Shumby congratulations. the first GTM SC in Canada.
I think that you should make a detour on your way home and give RCZ a ride in your car, You can tell him and show him how good the GTM is.
I'm sure Sam will pay for the gas.
I'm sure that he would love to see you.
you guys could kiss and make up.

shumby 06-10-2010 11:40 AM

lol. good one Z elim



On a side note about the air intake temps. you also have to remember that the intakes are now also getting cold air from the center bottom grill as there is nothing blocking this. If you were so inclined you could even add a difuser to iect more flow.

Z eliminator 06-10-2010 01:17 PM

Waiting for the dyno of your car

RCZ 06-10-2010 01:28 PM

lolz...

Neo187H 06-10-2010 04:27 PM

Anymore info? The suspense is killing me.

Speaking of BJ's - since you are in the LA area, check out BJ's restaurants.. :tup: Good food.

shumby 06-10-2010 05:13 PM

lol it is killing me too. but it is alive. \i heard her start up just a few moments ago. \SOOOOOOOOOOOOOOOOOOOOOOO excited

JB-370z 06-10-2010 06:02 PM

Any more pics Shumby??
Can't wait for some videos!!

RCZ 06-10-2010 06:04 PM

video!

jnaut 06-10-2010 06:06 PM

... wtf is going on?

shumby 06-10-2010 06:12 PM

lol hold your horses guys

jmlenz 06-10-2010 07:51 PM

tick tock tick tock...

jnaut 06-10-2010 10:57 PM

doesnt take 3 hours to upload a damn video...

Valentino 06-11-2010 03:14 AM

Videos... Videos... Videos... Videos... Videos... Videos...

Zsteve 06-11-2010 07:39 AM

Show me the .........VIDEO. So how is the useable power and how quick does it come on?

Z eliminator 06-11-2010 09:27 AM

Shumby. RCZ wants to see a video !!!!
Its sounds like he may change his mind and get a GTM SC if he likes what he sees.
Why else would he have so much interest in it.
I think that you and him have "something going on "
Im sure that Sam would give him a Special price on the SC.
Sam called me last night at 1.30 am but i missed the call, can you PM me with the dyno results.
Thanks
Z.

Hope you're joking.

I want to see a video because its a video of a supercharged Z34 and that's cool no matter how you cut it. I already have a Stillen one installed and the car is running, just needs to get tuned.

Funny how you're talking about me like I can't read this lol and funnier about the special price from Sam. Why do you think Sam wants me to get a GTM SC??

Come on now, just stop :stirthepot:

Hopefully this car is ripping around the streets somewhere already.

shumby 06-11-2010 11:49 AM

sorry no vid yet. it is still on the dyno. it will be done today if the tune goes as planned.

JB-370z 06-11-2010 01:03 PM

Shumby:
You cannot give a build-up and not deliver :) j/j....
I am sure GTM will give you the best tune of all the tuners here in the states. Cannot wait to see what the numbers and psi levels are with those LTH's.

shumby 06-11-2010 01:54 PM

LTH + SC = Major fail


FML

How so? Need more details, because long tube heads are pretty much the standard on other cars for supercharger setups.

shumby 06-11-2010 02:02 PM

only building 4 psi. the headers are not allowing enough back pressure and is basically not allow the boost to stay in the cyclinder. stock headers and cats going back on the car.

JB-370z 06-11-2010 02:04 PM

I knew it was going to lose boost, just did not know how much. Ouch. So whats the plan now?
Edit: Sorry to hear this just got to your above post

Hmmmm.....

rednek01 06-11-2010 02:11 PM

sounds like somebody needs to figure out vvel...

shumby 06-11-2010 02:12 PM

ya if that was cracked this would be a non issue

I know with the new 5.0's we are allowed to play with each cam individually and its already been unlocked. so we can have the lopiness sound of overlap while readjusting the cams with throttle tip in to optimize. Pretty cool stuff. We are working on putting very aggressive race cams in and then using the "ti vct" to adjust them to be mild for daily driving.

theDreamer 06-11-2010 02:32 PM

How much rear wheel HP were you putting down with just 4PSI?

shumby 06-11-2010 02:34 PM

To tell the truth i was too upset about the boost numbers to ask. I was too worried abotu calling the wife and telling her the bad new.


Just want to make this clear. this is not GTM's issue i rolled the dice adn it came up snake eyes. Now you all get to learn from me.

But lower PSI is more efficient with better flow, you should be checking the HP & torque numbers to see how they came out. The car may not want to go beyond 4PSI which sucks, but you could be putting down good numbers at 4PSI; we just have to wait to run higher PSI for more power.

Did you at least get a dyno graph? having only 4 psi doesn't tell the whole story. I understand your upset but you should have gotten numbers and such before hand so people can diagnose whats going on.

JB-370z 06-11-2010 02:39 PM

Sometimes it cost to be the pioneer. You win some you lose some. Sorry to hear these fustrations Shumby.

shumby 06-11-2010 02:41 PM

From Sam i know th enumbers were not anywhere near where we wanted them. So really i do not care. I want the best out of this and this is what Sam sugests to get theat. I trust him fully. he did warn me about the LTH and that it might be an issue. We just did not think it would be this much of an issue

shumby 06-11-2010 02:42 PM

thanks JB. I knew this couls happen. Just wish it did not happen on my 5 year mark with the old lady. lol. the cost of this is nothing compaired to what it will cost me when i get home.

bullitt5897 06-11-2010 02:45 PM

nevermind read your new post lol

these are two totally different animals the 5.0 and the VQHR especially down to the tuning aspect.

Domestic sports cars are built so that the aftermarket can really pump them up... its been that way for decades.
