House's ITB XE build and re-build

[House]

PH5's mate. I'm told they're a little tasty!!!

[TallDave]

Just checked out the spec on the PH5's (yes I'm a full blooded anorak, what can I say!), so your not going to be pussy footing round the track then, with a rev range of 4 to 8k you'll need to get the lead boots on next year

Love the head, I've got my own Coscast stripped down and just begging to be given the same treatment, if you don't mind me asking who did the work, your engine builder or someone else?

Have I missed your proposed engine spec? If not, I don't suppose you'd like to give all us slavering types a run down of your build plans, slurp!

Keep up the good work.

Hey Mr Tall, I'm not gonna go into all the hassle I had with the start of the engine build it's well documented on here!!! but as far as I know the initial headwork was carried out by Steveboyslim on here, with hand finishing by He who must not be named, I believe Mr Steve has the Swindon Racing Engines jigs to do the port boring and then the chambers and ports finished by The dark lord by hand.

Despite me pointing out flaws in He who shall remain nameless' business practices and some of the quality of parts he was using for my engine, the boys at Modus have given the head work the double thumbs up and are really impressed with it.

The basic run down is :-

Early XE block
86.5mm super tech forged pistons
Williams rods
Early crank
12.5:1 CR
Coscast head port bored to SRE specs (So I'm told)
Newman PH5 inlet and exhaust cams
+1mm wasted stem inlet and exhaust valves
solid buckets with Piper double valve springs
Modus lightened flywheel
Helix 4 paddle clutch and cover plate
Everything is being balanced
All running through my Jenvey direct to head Throttle bodies with blue VXR injectors
Mapping and running in will be by Track and Road

The levels of detail Darren and Jay at Modus work to are amazing, everything has been stripped, all oil galleries scrubbed, the engine will be cleaner than when it left Vauxhall!!

I'm not sure on power output, the old XE I built with QED Q42 cams, no real head work and 11:1 CR made 201 at the wheels so I'd say maybe 225 at the crank, these PH5's are more brutal and the CR is higher along with the head work I'd hope to see over 230 at the crank but don't hold out any hopes regarding final power.

I wouldn't be surprised if the head was done by Neil Roper ,I am led to believe he is known by Steve and is one of the best in the business

[House]

Possibly mate, I don't know exactly who did it but it is pretty bloody good!!

We'll see soon enough hoping to be in the car for end of Feb!!

[Rob H]

Good spec on that engine! What you gonna rev it to?

[House]

Thanks mate, rev limit will depend on the power curve when we map it. The balancing will be good enough for 10k but the crank wont do that, reading up on the cam info 4-8, I'm guessing somewhere at around 8250 but we'll see. It scares me revving that high so I'll not be going up there too often!! hahaha

[Rob H]

Nice! Should be a barrel of fun when it's ready.

Once it's all working i wanna see vid's with IaIn behind you on track...

I'll be honest I'm surprised we weren't black flagged at Snet & Donny, it was blatant that we were having a little go with each other and it's supposed to be no racing!!!

Iain has the edge at the minute though, bigger balls I think, I'll just have to catch him down the straights!!!
