The torque is looking great, I wonder with HFC you can get it up to 400HP without losing any torque. Thoughts?

The 6 psi is purely related to the size of the pulley right now, We could have gotten more psi by going a smaller pulley, also we have to remember that the 390 RWHP is equivalent to about 410 RWHP on a M/T car .

You can get more boost by going a smaller pulley but for a guy that drove 2300 miles and waiting on his car in hotel room on us to finish the work, I felt the 6 psi is playing it safe right now. there was no room to for anything to go wrong .

Sam

Take the same combination and throw it on a M/T car and a Z not a G and you will automatically make more then 400 RWHP.

Big mistake on his part. When you take your car significant distance to have a specific shop do the work, it is silly to take the ultra conservative route. He could have found joe blows shop down the street to do that. He should have planned it out better so you had all the time you needed to take this farther.

390 is a ho-hum number and I look forward to seeing future builds at 8PSI+ on a G37 before I make my choice of kits.

I was expecting more, cannot lie. Its nice and all, but why wasnt the full 8 psi hit again? I mean I know you said you wanted to be safe, but wasnt 8 psi the number you advertised and have spoke about being a safe number?

I understand that, but from what I remember 8 psi was playing it safe, so 6 psi seems like total and EXTREME overkill

Customer is always right though.
Shumby wanted certain numbers so Sam did what the customer wanted, I am sure if Shumby said 8PSI safely Sam could do it.

so does the kit come with the smaller pully to get the advertised 8 psi? Or do you have to buy it? I dont remember seeing anything about that in the ads,

We have multiple pulley options 4,6,and 8 psi . you can choose what ever psi you want to run.

Sam

So is 8psi not safe?

Sounds like shumby was on a tight schedule.

I think you are missing the point, My concern was not the boost or the Hp numbers, the concern here is the torque the car made 340 RWTQ on a stock 7 A/T . couple more psi would have been over 360 RWTQ . for a stock 7 a/t and a customer out of the country waiting on the car, i was not willing to take that risk .

Beside shunby was happy with results so why take a chance .

Sam

Have all you guy forgoten that shumby's car is a 7 AT. He is the first GTM on a 7AT. The block can take 8 psig but what about the trensmision? If he blows a tranney on the way home im sure that he would not be happy, Sam did the right thing with the 6 lb pulley. When he gets a VB and torque converter in his car it will be ok to step it up to 8 lbs of boost.
My 370z 7 At has 320rwhp with N/A modes and it very fast. It can be a hand full to drive. 380 rwhp with a lot more torque is a very fast car. Shumbys car is going to be close to high 11 to low 12. second 1/4 mile car. Thats awfull quick.
Mine should be shipped to me soon. it will come with all the 8 lbs goodies, oh sam i can not wait to get it.

:iagree:

Not the way I would have went. There is such a thing called a pedal which allows a person to modulate the power.. :icon17: Driving 2300 miles or whatever, I would have wanted the end game setup with trans mods coming down the road.. Not lets add more boost later and hope the tune is ok or can be adjusted well remotely.

As for blowing it on the way home, it doesn't matter if the car made 200hp or 600hp - if you drive it normally there is no worry. Getting it home fine is not a valid point of consideration.

MMC racing. Do you drive a 370 or a GTR. You have to remember that us Candians drive very fast up here in God's country. A 370z only has one speed. ( wide open). We like to drive them wide open. With that nice cold air in Shumbys province his car will make more RWHP.

i can not wait to take mine to the drag strip.
" soon to be a stock GTR's worst nightmare"
11.7 here we come.
305 35 18 drag radials ( should have gone with larger tires)
Sam I will be needing that 10 lb pulley !!!!!!!

So I have heard that the 7AT is the same tranny as the Infiniti M56 and that handles well over 300 TQ, is that right?

GT-R and G37.

what about a chipped GTR?

So are you going to chipp the GTR or any exhaust mods?

Been down that route, then demodded because I was going to sell, and now keeping and remodding the car. In the next few weeks I'm doing intakes, injectors, pumps, downpipes, midpipes, and tuned on E85.

DD is the G37 though and I'd like a little more get up and go so I'm watching the progress of these kits.. We sold our Vortech powered 350z earlier in the year.

So what was the GTR like chipped and modded? Alot faster than stock?

95hp gain. Huge improvement.

MMC. you are totally missing what i want out of my car. I am happy with the 390 HP and the TQ. could we have gone more yes. Did i drive it normal all the way home no. I drove 2300 miles in 24.5 hrs. only stopping for gas and redbull. did not even stop to eat. I needed to be home to get my passport out for a work visa and did not have time to waste. I was not going to be happy with 8 PSI without a TQ converter and a VB upgrade. Why I would go wth the 8 PSI pully now and risk damaging a Tranny on my way home and then looses my job because i did not get my work visa in time is beyond me. Or have my wife drivng the car while I am away and have the tranny fail because she was pushing the car too hard was not what I would call Smart. Weh i get the VB upgrade and a new TQ converter I will go with the smaller pully. But not until then. You guys forget this is a DD. NOt a track car. I drive this car and put more miles on it then 80% of you guys. This is what I wanted to do and the numbers i wanted to get. Will i go bigger later? Yes. But not until I am happy with the tranny and how it will last.

Now get back on topic and stop talking about the GTR

Hey all sorry needed to take yesterday and just chill and get my wifes to do list finished up. Wow oh wow i love this SC. The car ran like a champ. 2300 miles in 24.5 hrs only stoping to gas p and buy redbull. No i did not even stop to eat. So that should speek to the drivability and endurance. I also drove through 5.5 hrs of heavy and i do mean heavy rain. No issues with the intake location so that should put some fears to rest. This thing has balls and I love it.


The Car is at the dealers right now getting a tranny flush and service. Only 3things I have notice so far. First the Camp 2 was installed and now the GPS does not work. This is a simple fix with adding a couple switches and Sam is getting the correct info for me so I can do this. Second was today when the car was up on the hoist the oil filter had come a bit loose and there was a small very small oil leak. This again is not a big deal and no a real issues in my books. The 3rd thing was that the car started very hard after hard driving and then letting it sit and heat soak. Again I just told Sam about this 20mins ago and he is getting my the reflash to take care of this so again not an issue.


Over all very happy with this move and might see about getting the PSI up a bit more once i see how my tranny handels the extra power. I have a loaner G37 coupe right now and let mwe tell you it is so awsome to see how much extra power i really do have. I got in the loaner and went to step on it and it was like i was in a honda. lol


Pics and vids to come. the car is really dirty right now and stoill not washed from the trip. it should be washed today will get some vids and pics tomorrow at the edmonton mini meet.

I never thought for a second that this was a track car.

It's fun having the extra power isn't it!

avg over 93+ MPH for 2300 miles?

I have done it for 1200 miles so its not unheard of... i also got close to 30mpg at that speed which is unheard of.

You dont happen to own any M3's do you?

Let's keep this on topic please.

Thats what I thought...

This car isnt yours and I could care-less what YOU would have done. A shop can never assume a client will baby his car back and I for one am glad they took the time to explain that it may be reaching the limits of the stock A/T. Smart move and proved to hold true considering how this mad man drove back. He can do the upgrades later and reflash remotely. Not as big of a deal as your making it out to be.

Shumby - I'm glad YOU got what YOU wanted out of this car. Not only is this a testament to the potential of this setup but also cements the claims by GTM. Especially for us 8psi - M/T guys.

So is this the 8psi pulley?

Congrats Shumby! Glad your car is safely back home and youre happy with the way things turned out.

no it is the 6 PSI pully

so I hear that the tranny might not hold up on 8 psi but again isnt this the same tranny that the infiniti m56 (or whatever it is) has and that handles like 350 TQ stock, so why would we need converters and all? Right now after hearing what Stillen wanted for theirs and now the ATs not being able to do 8 psi cuz of tranny failure I might have to rethink this. If I spend this kind of money I want over 400 whp but I want it safely. I guess I will have to wait and see how others are doing.

HOld on here no one said it was not safe. It has not been tested so I was not comfotable with it. I will be moving up to the 8 PSI pully but i want to make sure. I always play things a bit on the safe time. I am not really in a hurry to get my car 100% where i want it. ( don't thtink it will ever be there to tell you the truth). This gives me time to hammer on the tranny a bit and if nothing happens bad i am going to go to the 8 PSI pully. Do not let the fact that I am going with only 6 PSI stop you from getting this. I am just a bit more slow to jump into things then most. plus I am awa alot and don't want my wife dealing with any issues with the car no matter how small. (cuz she gets really mad).

How much did your MPG change after the S/C install on your road trip?

you know i did not really calcul;ate it. i just drove home as fast as i could. plus my fule sending unit was bad and miss reading yet again. (got replaced today at the dealer) so i could not even really tell what my real fule level was
