I'm using a full supertech valve train with inconel exhaust valves and stainless inlets 0.5 oversize. I would have liked to use ferrea but it's bloody expensive stuff, I don't really want to use the standard b16 cams as from what I have been told they are pony for boost, ideally I would like to use pro1's but we will have to see what Santa brings. I can't build it up fully yet as I need some new lma's, my head came with the old type obd1 Lma's which can stick and cause a racket. The spring type lma's from the nsx are the ones I'm going to use as these work better with high lift cams.

Ive been looking at some supertech springs with T1 retainers, ill keep stock valves for now.. Our Lma`s sounded fine when running so ill just re use them aswell... along with stock cams :( just dont have the funds to improve with any of this yet.. could problem pick some cheap gsr cams i guess... maybe you could just find some C4 cams for know, i know they aint the best option but like you said, these will be better than yours now.. just get finding a shell mate!!! :)

It is now at the top of the things to do list along with a turbo so I can make a down pipe and screamer tube and a clutch so the gearbox can be bolted on and slung in the car. I down have the cash for a twin plate so will hopefully use a cc 6 puck sprung centre plate and hope it lasts.:scared:
Re: Project raider- semi o.e.
So many times in the past have I got pissed off with jubilee clips, either slipping with the driver or them breaking, I decided I could not have this problem when racing, I want it to be able to come apart quickly and be super reliable so I'm going to do the whole fuel system in -8 the main coolant hoses with -16 and the breather system with -10. I may also if time and money allow do the charge pipes with v-band clamps.

Just a few of the fittings I got from eBay super cheap with a load more on the way, I should have a fair few left so later on may be selling a few super cheap.
Re: Project raider- semi o.e.
I love the use of AN-X fittings, just make the whole bay look more professional and business like. It's the minimum standard on aircraft. :agree:
Re: Project raider- semi o.e.
Nice project thread RS ;)
What sort of static and dynamic compression are you going to be running? Head looks good chap. Have you looked at the TheOldOne website?
There’s some other stuff here you might like if you haven't seen it? The CNC blocks are nice. Some of the tech discussion doesn't quite tie up, but the results are there and documented. It would be nice to see results for acceleration pulls and what load the motors will take in a true dynamic than effectively static state.

Re: Project raider- semi o.e.
Wow some extreme work in that thread.... The orginal billet wheel looks like some of the 72mm cheater wheels in the outlaw class... :D
Re: Project raider- semi o.e.
Thanks Martin
The static compression will end up around 9.0:1 maybe a little higher as I had the head shaved a little. As to the dynamic compression I'm unsure, this will depend on camshaft selection and wether or not it's in Vtec, maybe. I'm on a real steep learning curve at the moment as I'm a pro painter not a pro engine builder and this is my hobby, that said it's this kind of input I need to help me get to the top of the learning curve:agree:
Endyn and RLZ do some nice cnc head work and would have gone with RLZ if I had not heard about there shocking customer service. Mike at Laskey racing offered me a good deal on a complete head package so went with him, all his head work is done by Port Flow Design in California who have been responsible for some top work for the likes of Cosworth,TRD,Nascar.
Some of the stuff in that thread are what dreams are made of, maybe one day if I win the lottery.
Re: Project raider- semi o.e.
Well your build looks nice, and look forward to seeing it come together :agree: Dynamic is easy enough to work out (excluding any ram tuning effects) and as you say need to know your cam specs. Static doesn't really tell you much, dynamic is more informative and will be able to judge whether you will be ok with what ever fuel grade you are choosing to run. You have a nice clean chamber, compact and fast burn so you will be able to be much higher than the old conservative dynamic 7:1 rule of thumb, but I'm sure you have some good advice on that already. Might be worth making a chamber mould though... see plug position, relative to the dome and flame front path, just a thought.
Yeah, know what you mean by dream dream dream... anyway, hope to see you out there next year.
Rob, yes nice compressors... on my latest venture with Clee I seem to be dreaming about compressor wheels.... sad init :laugh:
Re: Project raider- semi o.e.
To start with I was sure I wanted to use q16 or vp import but after seeing what these fuels do to aluminium parts due to their high oxygen content I steered clear, Im hoping on c16 if it's available at a decent price.

that would need some serious amount of boost control, 1200hp jump in 1500revs :eek:
i dont think any tyre could hold that :wasntme:
Re: Project raider- semi o.e.
I have just caught wind that the new 67mm efr from Borg warner is available in a t3 frame exhaust housing, something I may wait for instead of the pt 6765 :devil:

kinda why I think they were really loading in a static incremental fashion, would really like to see how this motor pulls itself up by it's shoe strings :)
What do you think of the Holset HX50 compressors?

Forget that cr@p ....
You want to be using this;
HIPERFLO TURBO ULTIMATE
UNLEADED RACE FUEL
RON 102, MON 90

Depends on its purpose.. That fuels developed to meet FIA regs for race cars and prob the best out there for them to use, they cant roll up to race events with Q16 sloshing in the tank.. and its dam cheaper than VP fuels.. BUT might be all well and good for alot of race cars but **** might hit the fan at 10:1 cr and 50-60psi boost. Think id still go for the C or Q16 or E85.. But then also there is not point in say a porsche 911 with 350hp with Q16 in the tank, completely pointless.. so Hiperflo would suit that car very well... All down to the tune and purpose... :)

Well I've seen back to back test's with C16 and this stuff and the engine it was used on made an extra 100hp with the hyperflo.. Still what do I no about fuels and your right every engine is different.. Just thought I'd offer a possible cheaper/better fuel :)

I have not really looked at holset turbos much, the one you mentioned won't flow enough for the power I'm looking for. The precision and Borg warner units seem to be smashing it in all classes of drag racing at the moment. The new Garrett gtx range of turbos sound promising but have yet to see any back to back comparisons.
