Fellow Turbo nutters, what do you make of this?

[PJR]

There is something really cheesy about this video, but try to look past that and see what you make of it..

I don't know about you guys, but i've not seen turbo's mounted like this before.

P,

[steve_d]

Agreed I've not seen it done like that but it seems to solve a number of issues like space and heat in the engine bay. Quite a unique sound as well.
Nice power hike for a days or twos work but at what cost?

When I was at school we had a Pontiac Trans Am WS6 with one of these kits on it and had nothing but problems with its oil system leaking. Hopefuly the manufacturer have that sorted.

[That Daddy]

very unusual,but it works for sure,looks like quality kit as well.

[stevieturbo]

Nothing new about it really. There are thousands of them out there in the US, and some of them making incredible amounts of power.

Ive seen videos of some 8 second rear mount cars.

It certainly isnt the best place to mount a turbo, but you cant argue with its results.

For a lot of cars in the US, with dodgy emissions laws. The rear mount kits arecheap, and because they dont tamper with any emissions related equipment, they can get their CARB approval much easier. Which means they pass emissions laws in California etc.

As for saying at what cost ?? These kits are a fraction of a conventional turbo system, and much easier to install. A lot of modern US cars have very tight engine bays

There's a chap with an LS2 Twin Turbo Monaro, posted detials of the upgrade in the HSV forum with a similar set-up I think .

537RWHP from 7PSI is very impressive. They do make it look easy on that vid. I know the tuning on my SC upgrade took ages and is still not quite finished.

I would have thought they would have needed to upgrade the fuel pump too.

Thats the GenTT kit from Australia. Its a conventional front mounted turbo kit though.

The video is about a turbo install, with the blowers at the rear of the car !!!! Most of the kits will also come with a pre-supplied map, that you can load into the ecu. So tuning is taken care of. Its a mild/safe tune, but it still gets you on the road, with a little boost.

Shouldnt make much odds as to a turbo or SC install as to how long it takes to fine tune it.

[PJR]

Im surprised they claim there is no lag with all that pipe work. You generally see turbo tuners try to keep the pipe work as short as possible for this reason.

Also, does this set up not place a red hot turbo or 2 in very close proximity to the fuel tank? Would make me a bit nervous I think..
Not to mention the exhaust pipe from the engine to turbo is a very long pipe that will be red hot too I expect..
And another thing.. This setup puts the turbo post cat. I'd imagine this heats up the cat even more, so I would be surprised if this didn't shorten the life of it by quite some margin.
Very interesting none the less though, and was certainly news to me, even after reading some of the more popular Merkin car enthusiast forums.

I'd imagine this heats up the cat even more, so I would be surprised if this didn't shorten the life of it by quite some margin.(Quote,,,)That could do some interesting damage to the turbo vanes if the cats let go, dident think of that one,the cats would cope with the extra gasflow alright,not sure Turbo lag is such a problem when your using a V8 of that size though.

[stevieturbo]

Heat may be an issue, but temps wouldnt be quite as bad as seen in a normal setup.
A lot of heat would be lost due to the exhaust length.

Again, cats can be removed. But for the base CARB legal kit, they must remain, and its a very cheap way of boosting the power output by quite a bit.
For the base kit, I doubt temps would be a concern at all. it is only a mild upgrade after all.

That's amazing. All i thought I understood regarding having the turbos as close as possible to the engine so that the gasses had as much energy in them as possible was clearly all wrong. I'm going to buy a mini 1000 and put a turbo in the boot

I thought the only cars with turbos in the boot were Porkers!

been done already. Theres a guy in the US thats done it to a Mini. Rear mount turbo blowing through a small weber carb
Its been covered on the TurboMinis forum

Think it made a little over 100bhp.

Right, I'm going to take the turbos off my 993tt and put them in the front then!

[chuntington101]

guys dont laugh to much at these rear mount turbo setups. there is a corvette run by a guy called MajorSpray on the corvetteforum that run in the 8second 1/4 mile! also there are numerous big bhp guy kicking around on there and the ls1tech forum.

rear mount or remote mounting is ok for the V8 guys cos they have the Big cc to cover up any lag.

take a look at www.ststurbo.com for more info.

thanks Chris.

it is better to have the turbos as near as possible

the clip shows max power under best conditions in a race or spirited driving the boost will drop and take time to build

but they are only using 7psi and for the turbos to make that is a piece of piss

also there are no mufflers after the turbos so thoose are not ordinary turbos they are nice withe seperate waste gates properly setup they will make 800 to 1000 bhp on that engine and lets remember they are only getting 100 bhp per litre so they are not really doing anything much

they are taking a large engine with 2 valves per cylinder and bringing it up to 100 bhp per litre

honda do this without a turbo

any turbo without silencers after it makes large power

it is not the best souloution but it does enough to make it good for the ease of fitting

Everyone knows its better close to the engine.....but these are cheap kits, that are easy to fit, for mild upgrades on an otherwise totally standard engine.
Of course some people take them much further than that.

The turbochargers are perfectly ordinary cheap turbos. Just because they dont have an internal wastegate, doesnt make them special. If the turbos arent suitabaly sized, then it doesnt matter a damn what sort of wastegate is on them. They still wont make xxx bhp.
An xxx bhp turbo is an xxx bhp turbo, regardless of wastegate type.
It would be silly to put a 1000bhp capable turbo, onto an engine that will only ever make 500bhp.


And the Honda arguement has been covered in another thread. Lets see that 2.0 Honda engine lug a 2 ton American car about lol !!
In fact, lets see any torqueless Honda engine lug a 2 ton car about. They may make 100bhp/litre, but power alone isnt everything.

2 two litre honda vtecs in a v making a v8 with vtec

that would pull the 2ton tessie

............and that, with turbo matched correctly, would make a good engine for these type of turbo systems to be fitten to!

They would still be gutless with no torque.

some one should introduce you to the gearbox
