Really like the location and mounting brackets for the oil cooler and trans cooler. Any chance you will be selling the mounting brackets, if not any chance you could PM the dimensions to me so I could prefab them before my install. Are you guys going to look at installing vents for a pass through in the wheel wells? No worries about water ingestion with removing the blanking plate from the passenger side of the front bumper? Everything really looks great Sam, top notch work. The attention to detail is very impressive.:happydance:

What on earth is that plastic box looking thing to the left of one of the oil coolers? I see this a lot on G's and I have no idea what it is. And while were on the topic, what does it DO?

Interactive cruise control laser or sensor.

Whoa -- bargin! And it comes with decent injectors and a larger flow pump too -- sweet! :yum:

Little off topic, but anyone know if some modication to OEM bits is needed to fit the Walbro on our cars? I only ask because this is sometimes necessary...

NYBladeZ 06-08-2010 10:13 AM

^^I agree the radiator seems to lose about 85% of its surface area to the intercooler, supercharger oil cooler, and intakes. Btw, why does each intake have a cooler? Couldn't some of these issues with heat be addressed another way other than giving each piece it's own cooler? I guess time will tell, always nice when someone takes the plunge though and the camp II will definitely monitor everything so we'll know how it goes.

Buddy Revell 06-08-2010 11:32 AM

There are now TWO in-house GTM SC installs. I dropped off my G this weekend.:tup:

Well granted that there are things in front of it, air still gets through to the radiator and under normal driving conditions it should be enough to keep the car happy. When things heat up though, it may or may not become an issue. Those coolers are probably dual oil coolers, the piping goes behind them, not through them. There was no room in the front to put a bigger one, so they opted for two smaller side mounted ones. They look awesome on there and hopefully the side inlets of the front bumper allow enough air into them. Oh wait this is shumby's car? hopefully they don't then. ( I keed). Wonder how much weight all those coolers and fluid added to the nose of the car...

i believe the top cooler is for the rotrex SC and the sides are for the engine oil and transmission... so ur right, those might not be enough... but then again the g's front fascia allows more air flow compared to the Z.... i think the placement and type of oil cooler used for the robispec 370z could be a better set up to cool the engine oil but thats is more weight ... btw, sincerely :tup: on ur SC kit and looking forward to ur unbiased :p review...

For those of us doing reviews on GTM's SC, what issues/questions do you guys want addressed?

shumby 06-08-2010 04:44 PM

i feel the oil and tranny coolers are in a great location with the room upfron used to its best. As for weight to the nose. realllly? lol lol. RCZ you have fun with the stillen kit. i saw it in personand was not impressed but hey you seem to be the know it all.

shumby 06-08-2010 04:46 PM

not looking like it will be on the dyno today. unless he does it before he wraps my headers.


On a side note i will be interested to see what the HP will be with the LTH as after seeing my before dyno i don't think they were a good investment. only time will tell i guess. and hey it is only money. I got the car to have fun withand try new things.

No JB-370z, no one is starting anything. Just commenting and keeping things positive. No need for your comments.

First, thanks for not biting my head off haha. I hope it is enough for his sake. As far as I know he doesn't do much track work and lives in a generally cold climate so he should be OK. I wish we had something like the G's side vents. Rotrex oil cooler? I didnt know there was a cooler involved, interesting.

I am also looking to see how these GTM kits turn out, all bs aside, I hope everyone's kit works well and we can all keep enjoying our Z's. If anything we have benefited as consumers from the rivalry. I'm pretty excited to start ripping around town with mine and I'm sure that so are the folks getting the GTM one. Review will be coming, I'm not sure I will have much negative to say about +150whp, specially since I don't have much to compare it to.

I'm also as you said sincerely interested in the reviews from shumby, z elim and Buddy. I just hope they can manage to review the SC kit independently of Sam and GTM.

shumby 06-08-2010 05:57 PM

RCZ really GTFO

OK, I'll leave just cause you said so...:roflpuke2:

But really, all I was trying to say is that your setup looks good and I hope everything works well. If there's a problem with that then you need to get your head checked out.

NYBladeZ 06-08-2010 07:54 PM

So since I already have an oil cooler I'm going to need a new bracket and longer lines? That kinda sucks but I like to believe Sam foresaw this and has a solution in such an application.

Shumby, it's great that you opted for the camp II make sure you keep us posted you're review and experience will be huge.

shumby 06-08-2010 07:59 PM

RCZ you should be able to tell by now when i am getting bored and need some entertainment. Poking the hornets nest is fun.



I think that i can say that i will be putting the most miles on this kit then anyone so it will be a good test car to see about the lastingness (is this a word?) of this.

Z eliminator 06-08-2010 08:37 PM

Shumby if Sam as my SC ready to ship can you bring it into Canada for me.
I can not wait to see the dyno of your car.

thanks

bullitt5897 06-08-2010 09:59 PM

hahaha test ride and SC delivery all in the same day!!! :tup:

Sylvan Lake V 06-08-2010 11:19 PM

Lookin good Shumby :tup: I hope to see it in person soon, maybe you could take me for a drive. I think I am selling my 35 and getting a 37, if i do a trip to GTM will be involved as well :tup:

Driveability quirks if any.

Power potential is clear, but a real unknown is whether there are any hiccups in the tune, both on and off boost.

Just curious, but anyone know if those Sards are 4-hole injectors?

genki370z 06-09-2010 12:54 AM

everything is looking good so far! cant wait for the review on this bad boy!

Zat_Zuma 06-09-2010 08:47 AM

So when are you getting back home Shumby?

Really looking forward to seeing this kit from GTM

shumby 06-09-2010 11:15 AM

well getting home will now depend on how fast they can get my headers wraped. I have my 5 year aniversary on the 11th but i think i will miss that. Wife is not going to be happy

Baker 06-09-2010 11:18 AM

Car is look good shumby. :tup:

:bowrofl: The wifey is going to own your @ss :)
I can't wait to see the result with the LTH's. I have heard TheDreamers LTH's and they sound mean, combined with a GTM supercharger is going to be RE-DIC-U-LUS ;)

You left her at home :eek: I suppose she still has school:( you should have had her call in sick for a couple weeks :rofl2:

Zat_Zuma 06-09-2010 04:46 PM

Isn't she already a little sick with putting up with Shumby? :p

shumby 06-09-2010 05:45 PM

yes it does take a special kind of woman to put up with me. This install was not suposed to take this long but you know things happen and i did add in some extra work. It will be worth it in the end. The only thing i am worried about is the LTH i do not thing these will be helpfull with the SC numbers. but time will tell.

RCZ 06-09-2010 05:50 PM

wouldnt the increased flow of the lth help with power?

Btw, did GTM release maps for people with headers and upgraded cats? Or is everyone with those going to have to custom tune for the time being?

JB-370z 06-09-2010 06:02 PM

Higher flow in the header department can in some cases reduce boost on superchargers. As far as the tune goes, it would only make sense to save and reuse the tune that went into this build; for others with these LTH's but I cannot speak for Sam. Any word on this Sam?

Higher flow will always reduce boost, although it may increase power, provided the mixture doesn't blow out too quickly due to excessive valve overlap.

Boost is essentially a measure of restriction in flow.

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:

shumby 06-09-2010 07:28 PM

well just got back from the shop. it is almost all done. LTRH wraped and just bolting everything back together. testing and tuning tomorrow. woooot.
