the whole purpose of this thread is The DiRTy Risking Dave head and cam coffee table chat?

if its not im leaving

It would seem that way.

Dave if you have time on your side, there is a flow bench and equipement locally that I can line up for you. Just need to make a cam selection or try a few of the spare cams we have and make a decision based on what works with the ports you have done or want to do.

cool! yes paul it bench racing at its best :)

i find bench racing the most cost effective and easiest on tyre wear and brakes.

Speaking of bench...Santa dropped a new flow bench into our workshop over the break...got to learn how to use it properly now.

jun 2.7L

hks t04z 0.81 on trust s/s manifold

436rwkw on 18psi (98 pump fuel)

451rwkw on 22psi (98 pump fuel)

spark issues on 22psi so didnt push to rpm limiter (backed off at 7500rpm or so), more to come very soon with new ignition setup

when you say spark issues u really mean the chamber was ignited before the spark plug fired hey brad :D

How are you guys finding the results from the flow bench testing correlating back into the real world power figures? Its just a few of you guys were talking how NA cam and head setups are completely different to turbo head and cam setups however your still deriving results using vacuum based flow assessment.

My entry:

GT-R R33 vspec

Standard Bottom End

Standard Head Gasket

Standard Head

Drop in Trust 272* cams + Gears

Trust T88 Set up

Apexi Drag Cooler

Greddy Plenum

440awkw / 1134Nm torque at the 4 wheels on 26psi running PUMP FUEL @ Dart Automotive (New Mainline Dyno)

Motor Is still going strong...But managed to destroy a Trust 6 speed Dogbox hhhmmmm.....

:P

How does a combo like that go on the street, response and driveability wise (T88) ?

I'm pushing 330kw Atm and have turned into a bit of a power whore.. Lol

So im considering going the t88 route with one of the smaller rears, any advice ?

Cheers,

Mitch.

I'd like to know this also...

Anyone who's doing "RnD" want to weigh in?

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
