AMS's gt42rs+little friend, motor

[sean1.8t]

very outside the box on this one. unforturnately they were unable to tune it in time for the Castrol Top Shop Challenge they built the motor for.

they ended up going with a single 42rs and still won the competition. they sadly beat out 034/eurotuner for which i was really rooting for

but must say, quite amazing. i would have gone a slight bit of a different way and led the smaller turbo's charge pipe into the IM instead of the 42rs's inlet.

but hey, this is AMS im talking about. what do i know







and what they ended up going with to win the competition

made 1035hp on the engine dyno

[Kievskiy]

this is def not street legal, LOL

[Dday216]

how does that twin turbo setup work. i see the manifold running into the big turbo. but where does the small turbo get the exhaust from. and wouldnt the pressurized air from the small turbo just blow out the filter? is there a one way valve? am i missing something?

[Dday216]

ok i now see the exhaust inlet for the small turbo, but i still dont get why they send the pressurized air to the point before the big turbo.

[sean1.8t]

im not sure either. some type of motorized block off plate is what i assume that housing is on the inlet pipe for the 42rs.

this is also why i would have just gone with your normal sequential twin turbo setup like the RX7 and Supra guys do. have both compressor outlets flow right into the intake manifold. it would certainly be easier from a hardware prespective. but either way tuning will be a nightmare. but nothing AMS can't handle.

keeping my eyes peeled to see if they finish this concept here in the future

[audirs]

insanity

[chadb2434]

wow. ^he said it!

[pho1n1x]

that thing is so crazy I want to see them finish it

[Dday216]

P.S Those welds are sexy!!

Compound charging. That's what the diesel guys are doing for big...torque.

[milehighpilot]

i like it. i cant imagine the tuning issue... or still the lag time to spool that turbo... i wonder if once they hit the operating rpm range if the smaller turbo is just blocked off cause im sure it is out of its range....

torque. sooooo over rated

[Jdubya]

Guess you've never owned anything that actually had it. :)

its like a classic jdm twin turbo setup.. the small turbo is used for low-range RPMs while the larger one takes it all the way to redline. it almost looks like the smaller turbo is helping the larger one spool. lol. but even with the setup, i dont know how in the world that car is going to spool that massive turbo.

[Das General]

Is all of the top shop challenge info released? Link?

[sean1.8t]

owned no. driven a lot, yes.

my moms Maxima(02) and my brothers titan are very torqey. they both light up the tires very easy from a stop and sometimes slow roll. but after that, it's 20mph...30....40.......50.........60......wait.... 70..........etc.

it's just kinda an illusion on how fast it is. throws you back into your seat, but doesn't keep you there. my little 1.8t keeps you there..

oh, and same thing with my dads souped-up F350 and that thing has like 700 ft lbs....

massive turbo? for an evo? you must be new to the Evo world.

they made 800hp by 7000rpms. and 1035 at 9500rpms.. could have easily been taken farther and higher but they were limited to only 100 octane fuel and low boost (40-45psi rather than 55+ on c16)

same exact turbo 034 did on their 2.3L I5 motor and the 2.0l 4g63 had a lower boost threshold by about 500rpms.. but used an equal length twin scroll manifold where as 034 didn't.

Is all of the top shop challenge info released? Link?

the results are in the new eurotuner. 034 had some issues on dyno day though. might have placed better than third if all went well..

this is all i have for links though--->http://www.syntectopshop.com/

hahahahaha..........

I'm not going to lie, I was laughing also. I would classify my buddy's Duramax as torquey, putting down ~650 or whatever god awefull number of ft lbs is torque. A maxima, lol. Not VERY torquey.

did you read the line about my dads F350?

and torque is a relative term. as is horsepower.

it was a scenario of which the car has much more torque than horsepower. and what the care feels like.

but i guess it's over your head.

oh, and go drive a 02+ maxima. you'd be suprised

[Howard Hughes]

Sequential?

Horsepower sells cars... torque wins races.

[ROUGHEDGES]

my evo is pretty torquey. Bolt ons, stock cams, and pump gas.

made around 350whp/350wtq. at the weight of sub 3000 it moves out. I guess you need some torque to light up these 255s.

Dude I could do that with my last turbo making like 300whp/300wtq spinning 19s

[sean1.8t]

that's actually false.

torque is what keeps you at that constant 5mph in the pit area's.

hp is when you are flying at 7k+ rpms on the track reaching for redline.


think about it. a racecars's(or any internal combustion) motor makes peak tq between 2000 and 5000rpms depending on motor and components. when do you ever see a racecar on the track at below 5000rpms?

answer, never

the 30r b5?

[A4 TSCHUSS]

no my b6 with the gtrs on stock 1.8t engine running 93 octane and meth injection at 20psi which dynoed 301whp 300wtq on a mustang dyno.

My car is now the 2.0 stuff. That B5 in my sig which im assuming you are asking about is a friends car I drove. Stock 1.8t AEB with a ATP 3071r kit with tapp tuning. Havent got a chance to run mine at the track again since the engine/turbo upgrade

[biketsai]

holly shit, is that like a turbo for the turbo?

[ROUGHEDGES]

on the launches with the evo i have to backpeddle off the throttle to reduce spin. I had a s4 with xr chip running vp103, dps, catback, no cats, custom intake, ported and polished intake mani and heads, rs4 clutch and about 200 lbs in weight reduction. It didnt spin them close to the evo out of the whole.

[A4 TSCHUSS]

Who knows, evo is hundreds of pounds lighter than S4 though. I could leave like 20' of black marks on the road with my car. Now it is easier but I have a descent amount more power too.

[Jdubya]

that's actually false.

Then someone should go tell that Carrol Shelby guy he's full of sh*t. He obviously doesn't know as much about racing as you.

He's the one that "coined" that phrase.

[Maverick]

so AMS > Buscher Racing? true?

[sean1.8t]

so AMS > Buscher Racing? true?

hard to say. both have acomplished amazing things.

but if you go off of peak whp and track numbers, AMS > all
