Sam

wish it was an 7at!

No you don't. Without upgrades the 7AT wont hold the power.

Another Sick TTZ!!!

Sam you guys are crazy busy lol may need to get some more techs at this rate! :tup:

I'm sufficiently jealous.

Superb photos. Great results!

Coop

:gets out pen/paper:

Please list said upgrades lol :tup:

I love how stealth this thing is. Looks almost completely stock.

:drool:

Thanks for such detailed photos!

Very awesome. Wish you all would run the dynos from the same RPM point though. I would like to get an idea of boost/tq onset.

That is sick!!!!!!!!!!! If anyone would like to donate to the "I need one of these funds" feel free to PM me. LOL.

whoa that's nice!!

Sam I'm waiting for your email. ;)

I just listen to the slick music in his vids...... pics are cool too.

Same user name Alex brings old memory back , are we stroking this one:tup:

Sam

Rpm in the turbo set get up faster but will try to do that next time .

Sam

amazing! was anything done to the fuel system?

You don't forget the first VQ you stroked... :tiphat:

let's start simple for now...but "upgradable". ;)

Alex

Looks really good Sam!

Paging Sam, come in Sam....

My 7AT goes under the knife a Hills Garage in Maryland. Your stage 2 TT kit is being installed after I finally got off my patootie (My mother calls arse, patootie) Please send Frank some positive boosting vibes, mang!

Come on Alex I need a Twin :tup:

all that power on stock internals, I'm impressed and hesitant at the same time props to GTM for pushing the limit once again.

Nice! I saw this vid a few weeks ago, and it's nice. The display location is exactly where I would like to have it, but hopefully keep the cubby lid.

:icon17: You're too baller for me...

How fast are you guys completing an install these days? looks great.

Beautifully setup!!

You'll be surprise how tough stock internals are. My bud used to have a '99 1.7L Honda Civic running 1.2bar (about 17psi) on stock internals. The engine is still running fine after 2 years till he sold it. I had an '04 Alfa Romeo 1.6TS running on 1.6bar (23psi) on stock internals as well and had braced myself for a blown engine probably weeks later but heck i was wrong. End up i had her for about a year before i let her go. She was still running fine.

Makes me wonder after that whether all the $$$ going into forged low com piston are really worth it. Well, unless it's a 40psi drag car that's a different story. But having said that, gearbox are always the first to go rather than the engine.

Hey, I went for a ride in that car.

Chris, I am putting down the same numbers AND I HAVE A 7AT. Idiots.....yes IDIOTS like you are bad mouthing the 7AT when the reality IS only the SC installs had issues with the 7AT. I have over 2000 spirited miles of driving on my TT 7AT and have had NO SLIPPAGE or tranny trouble.

Bottom line......since you dont even have a TT please keep your INCORRECT opinion to yourself!

P.S. Wow......you are stupid!

:facepalm:

You need to read the rules my friend, and learn to control yourself.:shakes head::shakes head:

As they say "not owning a TT and having an opinion about a TT is ignorance"

So, every day must be blissfull for you!

LOL LOL somebody is getting a warning do da do da lol. Chris info is the truth lol. You are making your assumption off of only 2000 miles? I told you before your day is coming. Shumby had 2000 miles on his car with the SC 24 hours after installing it. No one said that if you install the kit the next day you are going to have a blown tranny. The truth is the tranny can't handle it for long periods of time. Go read sams post about it and you will see. If you are ignorant to ignore THE BEST AFTER MARKET COMPANY then I am sorry. The 7AT clutches in the higher gears are not strong enough to deal with the constant abuse and thats where the tranny is failing. There is nothing anyone can do atm for the tranny since no after market parts are there yet untill sam devlops them. So for the time being people that want to TT or SC there cars just need to be a little more conservative or they are going to be looking for a new tranny. These are the facts and you need to accept them. If you can't get a 6MT

PS OHH yea I own a TT just for the record

Well congrats although you seem to have a nicely built car you've hurt your credibility on this forum. The truth of the matter is that 7AT's in their current state cannot hold up to the massive increases in torque. I hope your luck holds out the I'm pretty sure that when your tranny does go you'll quietly fade away.

:icon18::icon18::icon18:

Wow thanks....with so many haters on this forum I sure am worried about my rep....lol! I never talk crap, I only talk about what I know. I KNOW my tranny is still fine after 2000 miles. While I am spirited when driving, I am not abusive to my car......if something doesnt seem right, I dont keep driving and it goes to Z1 ASAP to be looked at.

In the end, you haters could be right and the 7AT might be the weak link when doing FI.......but, if mines still fine, in my world your still wrong. Its obvious that others have had problems but, when adding this much HP and TQ there are many variables involved that affect the long term durability of the egine and tranny.

Haters LOL. Man why are you so bitter? All people are doing is giving good information and you are flying off the hinges. I don't know why you think it's a insult to you. I am not going to get made when people tell me hey your stock clutch is going to go bad, Because it is the truth. I have over 2000 miles on my car with the stock clutch but the truth is it wont be able to handle this abuse over time and I will need to upgrade. Are you catching my drift and what others are saying? Relax and hope for the best but expect the worst. Worst being new tranny parts to handle the power and the best being it will last for another 2000 miles.

:rofl2:
You might want to take a step back and see what people are writing, instead of just saying people are haters.

Bro, I'm still on the young and slightly immature side but you sound like a real dumb kid. Granted you might not be but you sound pretty immature using statements like "in my world." If you haven't already, grow up and learn how to take advice and constructive criticism. It is a public forum with many qualified opinions including those who have developed your TT kit.

I do listen and in general dont start trouble. On the previous page someone stated "the 7AT cant handle the power" and at this point thats not true and unfair because mine has and still is. That poster shoud have added "some" to his statements about the 7AT. Also, everyone keeps forgetting that the 7AT problems that have occurred are with the SC not TT. When I point this out to the "haters" their comeback is always "power is power" "HP is HP" "TQ is TQ" but I disagree. The TQ and HP curve is slightly different from a SC to a TT. Could this be the difference.....I dont know and neither does anyone else. My car has been TT'd for about 1 year and roughly 2000 miles and has had no tranny issues like the SC guys. Could it happen down the road.....maybe......maybe not. If it does, I wont shy away from letting everyone on here know I am having problems. I dont like Nismo's or 6MTs or body kits on the 370 but you dont see me bashing others that do like them. Until we "actually know" what caused shumby and others 7AT failures, we cant label the 7AT as at fault or bad or cant handle it.

Getting back on point, lets discuss those stock internals. I know we haven't seen one blow up due to FI yet but clearly it is a concern when power gets that high. I believe every high powered GTM built TT has installed a knock sensor so while they are confident they are proceeding with caution.
