Me too please, then drag slips cause dynos lie

Twin turbo fan boy

[The Bogan]

Yes Joey, drag slips, its the only way to be sure, I'll race you for beer (no more little bloody donuts, bastards).

You will though need to spot me 5.5 seconds though.

I'm guessing you might run a 10.5ish where I might run a 16ish

Come on, my 5 has at most an astounding 80 to 90 killerwasps at the back wheels.

[GTR_JOEY]

A dare say you could possibly win that drag race mark.

I don't know how many launches my standard box will take haha

Plenty. hardly ever hear of first popping.

Put It this way, my old RWD boat on old drag radials and 380kw got a 11.008, I'm sure there's a 10.5 in yours.

The box should be fine for the first couple of runs, it might sound a bit like industrial exhaust fan after that though.

In all honesty if you take off easy and don't shift to hard the box should be fine, I believe its the drag radials and big launches on the sticky stip that eats the 1-3 gears.

Ill give you 4.9 seconds then, with a 6 pack of Crownies on the line.

EDIT: First gear?, with your torque the only time you will use first gear is in the lanes before the water box

[GTR_JOEY]

Righto,

take this as you will, i consider that engine capacity, cams, fuel makes it a "similar" comparison

So same dyno

Both set ups have

2.6L

both have standard compression from memory

similar drop in cams

high ethenol content fuel

Both have large sufficient exhaust, ignition and fuel setups

Mine is the orange/red line

-5 line is black

To be fair, that -5 result im comparing against wasnt the most responsive run out of them all. But that particular result did flatten out alot after 5200rpm and my curve was still fatter

I dont know if i want to test the waters.. maybe when i get a stronger box.

I would have just got the thing on the road and i dont feel like spending more $$$ to keep driving it haha

[The Bogan]

LOL, Ive been there, fair call.

BUT, when you get a box its gonna be on like donkey kong

[GTR_JOEY]

you will be one of the first to know mate dont worry.. you'll probably hear me drive past the yard haha

[Stixbnr32]

Oh yup similar looking results to what I got just bait higher because of the ethanol.

I might stick with the -5's until i upgrade my injectors/gearbox and then go with a 8374 1.05 A/R as my bottom end has been built to withstand hell.

and I hear you about popping the standard box. Why I haven't run mine yet.

It's interesting to note that there is very minimal change in power between E45 and E85 on our boost levels. It's only an extra safety margin..

I'll be running 50/50 as a more common everyday mix

[XKLABA]

Lol, lies, I see lies

You can't really compair single v twin cause to many veriables like intake and dump pipes etc, dump pipes are one of the biggest issues with turbos and it's hard to get wrong on a single, especially if you have a external gate, but very very easy to get wrong on factory mount twins

Even cam timing makes a difference

So it really comes down to personal preference and what you want from your car

[Aggroman]

face it Mick the twins are done! done and dusted LONG LIVE THE SINGLE!

[XKLABA]

Lol, as if, I would much prefer to be doing it with twins then a big single

[GTR_JOEY]

Big singles go harder though

[WantGTR]

SAU WSID meet on the 11th!!!!!

keen to race my stocker nugget!

[GTR_JOEY]

Mine won't be running

[XKLABA]

Big singles go harder though

Haha, maybe, doubtful but maybe, but twins will get you there quicker

[Mick_o]

Depends on what single on what sized engine

But im of the opinion you only need 1 GOOD turbo and its bye bye twins

[Piggaz]

Haha, maybe, doubtful but maybe, but twins will get you there quicker

Take matty from WA's experience. Twin -5's on a 3.0 and went to a 8374/0.92 internally gate single. The EFR was back to peak boost levels in a 1/3rd of the time the twins took (Motec logs), made more power everywhere also.

However, it would be interesting to compare something like the 8374 EFR to say twin 6258 EFR's.
