My new turbo install

[Mike T]

still there - me too!!

 

[Mike T]

Well - here an interesting fact - it would appear that the limits of the standard/albeit polished heads are about 400 bhp.
Anymore than this on not possible as the exhaust ports and valves (possibly cams) cannot cope with the flow.
This results in more boost with no more bhp - bit like a blockage in a pipe - and a bhp peak at only 6000rpm.

Now 400 is plenty and torque is fine (very) from 2500 up but obviously there's a need to develop a more effecient motor.

On paper the turbo and chargecoolers are good for 650 which is taking the piss a bit in a car thats 3 yards long.

So its off to the Scott shop for a steel bottom end some serious head work, good job there are plenty of spare engines about! Another 100 bhp is comfortably in there somewhere with even more torque.

The drawing board beckons

so how long until we get to see this stage of the project finished?

i'm on the edge of my seat here, you're killing me!!

 

[Mike T]

that'll take months - I'll drop another motor in after the summer, this one won"t hang around!

Well Mike, back to the supercharger then, everything you mention points towards this.
I'm just a bit surprized about the airflowlimit of the cilinderhead., or is this with the additional manifolds?

 

[Mike T]

This is with trophy manifolds, standard cams and exhaust valves and just polishing , no porting.

Torque curve/boost curve is much better that the charger (30%+) across the range - why return to the charger?

It's just simply hitting a wall at 400bhp which is exit flow restriction at higher RPM.

and it would appear has been traced to the turbo housing which is being raplaced with a bigger one on friday - drove it today - mental and sublime in equal measure, traction control is the mutts

I must dig out my video camera................. [smilie=icon_eek.gif]

 

[Mike T]

indeed!

 

[Peter255]

Bagsy a ride in this when running anywhere near its 500BHP potential!

I'm only round the corner!

PS I have a high definition bullet cam setup! :wink:

so has the new turbo housing made a difference Mike?

 

[Mike T]

not on the car yet due to a little moment in the wet - be with you shortly!!!!

 

[weeian]

are u building this for 1/4 miles ? look forward to seeing a vid of it. u must have spent a fair bit to get this far m8.

 

[Mike T]

no, built it for a laugh.

I dare say it'll do a decent 1/4 and somewhere around 4 to 60 with LC and TC on

IMO darg racing is fairly boring, but you gotta try one 1/4 when its all back up together! :wink:

If your clutch can stand it i'm sure it'd be one of the quickest clio's out there! Maybe that TT engined FWD clio would be quicker on slicks but i can't see any other road registered clios coming close!

Any update?

 

[scala]

I hear that Mike's car was featured in Fastcar magazine - anyone know which issue or perhaps there's a repro of the feature online somewhere?

Thanks in advance

 

[Mike T]

fast car and more recently performance tuner last month

 

[Duncan]

saw the performance tuner article, was really good! what a crazy motor!

please bring it to a local meet sometime mike id love to see it in the flesh!!
