Hunting big power

[Haggarty]

This sounds epic, ill be honest my knowledge of everything happening under the hood is minimal. Cant wait to see what this widebody CF kit is going to look like! tucking 10's FTW!

 

[Fred@BTM]

you don't seem keen on naming anyone LOL!

From memory i believe the top boys in france moved the inlet ports up in the head massivley, the stock port position just couldn't do anymore than 250beans

Do they block off the water gallery between the valves to straighten the port?

LOL here's a glue then. The guy that designed my cams and did the CNC port flow maching, also did the heads on the 2 x F1 world championship winning Mercedes engines while he was in charge at Ilmor 1991- 1996, I am sure that you can work out who it is from there.
He disagrees with your statment that the ports have to be moved to achive more than 250BHP. heres a link to one of his F4R heads at work, not as high a spec as mine but close.

I am sure you will agree while the near 280 BHP is pretty impressive whats really inpressive is the fact its done at only 7600 RPM

 

[Silent_Scone]

aaaand that engine cost him the grand total of what exactly


/jealous

 

[chrispy.clio]

That's quality. 280bhp 

Two fuel rails seems pretty hardcore, I wander what mpg you'll get when your driving to the shops

 

[Fred@BTM]

Happy times!

I presume the cams are going to be fully phased? what's the lift profile on them like?

No Dephaser is used on the engine, as the cams were custom designed not to need it.

1.1 litres per mile at full racing speeds:evil: or at least thats what I got when I drove a test car at Brands although it was a tad more powerful.

Lol so 4mpg. That's lambo drinking

 

[Scrooge]

Absolutley cracking effort, I can't wait for the vids.

 

[cliobritt]

christ. this must cost a lot. my ek9 puts out 230 bhp and thats 3.5k of internals.

but for 300 NA?!!

 

[Wobba]

The old Sodemo F7R's used to make about 300bhp iirc. Surely the more modern F4R can manage that?

seems a lot? From memory F1 is "about" 1.25L per mile, we were 1.45L per mile LOL

 

[Nickson]

Seriously cool project!

 

[Wobba]

Seriously cool project!

I agree!

Rofl :clap:

Superb project. Any further updates?

well i doubt the power so ner :rasp:

stand off injection... I likee

RE the video / power figures
Is there much power to be gained from not driving an alternator (and presumably gearbox) when bench testing?

 

[hissingsid]

Did this ever happen ?

 

[harold chapman]

Did this ever happen ?

Yes it did and here is is

 

[EVOgone]

Any more pics with it moving!?

Just found this thread whilst searching for big valve heads, what did this engine finish making?

And regards who did the headwork, it says:

Well no Ilmor engines won between 91-96, it wasn't until 98 and 99 when it was under the Mercedes-Ilmor banner. Though I assume you are talking about Mario Illien maybe?? Highly unlikely he'll port me a head (Google says he's probably busy consulting for Renault F1!) but if I went to Ashford Motorsport who apparently used one of his head on that 279bhp engine linked, then I presume Ashford must be 'the' place to get a big valve head from? I'm massively sceptical of that power at those revs mind.
