any good?



200 escos-block with 0.5mm overbore
4x4 fully ported by jenspeed
std compression
rewelded intake manifold
2wd exhaust manifold
rs500 ic, kn-filter, moongoose ++
autronic sm4 with 4 msd coils and 1200cc injectors
bp320ht cams with vernier pulleys
garret gt3071R with 0.63A/R exhaust
1.8 bar boost

the engine is in a 2wd sapphire, and these numbers are at the hubs, measured with a Roto-test.

next mod will probably be a new exhaust manifold with an external wastegate.

 

nice!

 

Do you realy need 1200cc injectors for 440bhp? wouldn't 800s be enough?

(just realised it at the hubs)

 

the 1200cc injectors are there because the car is most likely gonna run Ethanol E-85 next year

 

440ATW seems like alot of power for a GT3071?

 

in what way, Christian?

 

In the 'I've never seen a GT3071 do anything like that kind of power' way!! LOL.

We consider it to be a bit of a pointless turbo in our (non-Ford) experience, but even a GT3076 would only do 440-480ATW in my opinion.

Please dont take offense.

 

Just to add fuel to the fire, the ginger jockey's audi turbo powered exige uses a 3071 and produces around 440 at the fly at that boost level.

 

Thats more like what I was expecting tbh. 440 at hubs on 2wd is gonna be nudging 500 at fly, so not beyond the realms of reality though?

There was Staffis old GT30 for sale on here a while back, and the seller said it would do 500+bhp, MAD even replied on the thread to confirm it was the one he spec'd and didnt say the power was off (might have been a 3076 though)

 

im sure someone see 530bhp at fly on one of those trying to think who it was

 

That won't be a 3071.

2.0 Evo's can make 500+ on a 3076, but the Evo engine is VERY good. I've also seen 500+ from an SR20DET 200SX engine on that turbo, but a 3071. in my opinion is on its knee's at around 420bhp on a 2.0 engine.

 

what fuel was this on?

 

In reckon the hub figure from that Dyno equates to what a Dyno Dynamics Dyno would use as an estimated Flywheel figure.

That car on our Dyno would make, in my opinion, 350-370ATW tops.

 

the measured figure is at the hubs, not on the flywheel. all done by one of norway's leading tuner/mapper on his trusty and calibrated Rototest.

would it maybe be any diffrence on the figures when measuring at the hubs, vs the wheels on a dyno with rollers?

mapped on regular 98Ron leadfree fuel

our mapper estimates 8-12% drivetrain-loss on the Rototest and said that it was about 490hp at the flywheel.

Can buy that ethanol E 85 here in Ireland at Maxol stations for 85c per litre!! Its 104oct. Anyone know what mods would be needed to the cossie to run it? I topped up the vRS with it last week and it made a big difference to power on it. Too much will prob blow the head off it.
