Project 'sillyteg'

[penski]

Its a bit different when your comparing bike engines in a kit car to a road focus'd VTEC car. Preferable means you can based either choice on what you require, lag is agricultural traction control for a little RWD i guess.

Just those VTEC ramhorn things are massive, and the amount of heat in the engine bay is a big concern IMO. Not an issue on that kit car.

I must have got confused and not got confused, seems youve always been an advocate of a log manifold. Turbos work on pressure mainly rather than airflow... unless you have bike cams

That blox item is pretty good, central WG, high Nickel cast iron made at the same place they do the Nissan manifolds.

I always thought that volume was king in turbo manifold design. Get the gases out of the block and into the turbo as efficiently as possible.

Talking to guys who design turbo installs for OEM and competition applications, they tend to agree...Other than the ones who are trying to eke the very last bit of top end out of a drag car.

Is that a US one from full race ??

Nah, Pang Cheung made it. http://www.pfabrications.com/

Tim, i know its not JDM, just wanted to understand the reasoning why you were'nt sure, the bling factor was the only reason I could think of. Turboing Hondas in Japan isnt as influential on the UK market anyway due to the language barriers compared to the huge market in the states.

I won't pretend I know a lot about turbocharged Honda's as its probably obvious I don't I just thought the ramhorn ones flowed better where the log ones are restrictive. The cast ones aren't repairable either are they, if they crack?

As little volume or most?

Efficiently isnt really the word i would use, the narrow cast surfaces with sharp corners over a tubular design. But yeah there more suitable. OEM is never gonna be guided by performance though, 100k+ life would be the main idea without melting the engine loom.

Thats why there good, they generally don't crack.

ah ok, but yeah bling never came into it, although I do wish my Seeker 4-2-1 was a shiny polished finish rather than dotted with surface rust

I contemplated adding 'as little as possible without hampering flow too much' but thought that I wouldn't need to explain that, seeing as all my other posts champion low-volume manifolds over high-volume manifolds.

Get it wrapped or ceramic coated! Stainless manifolds dont stay pretty forever!

OK, engine is in the car and 95% plumbed/wired in:

RC 650cc injectors in place:

Manifold, turbo and wastegate trial fitted:

I have also trial fitted the intercooler and oil cooler:

Oil cooler output sandwhich plate:

Getting there

 

[Dreadi]

looking sweeeeeet, i'm so coming to bristol when it done to see it in the flesh

 

[Lashout_UK]

Teeeeeeehehehehehe

 

[gobbo]

Not long till Japfest pal, better get working quickly!

 

[Phil W]

Great to see your DIY'ing it too, i'm sure you'll appreciate the fruits of your labour a hell of a lot more

Is the oil cooler really needed for road use, surely it'll just take the oil longer to get to a temp when you can have fun

...actually you're going to use this on the track aren't you?

Looking good!

 

[melchy]

When do you think you'll attempt to make the first test firing

You need to post a few clips once its up and running

Yeah I got it to keep temps down on track. I'll be fitting a thermostat to it so it only cools the oil when it needs to.

Hopefully I should be giving it it's initial firing-up by the end of this week. It goes without saying that I'll be filming it

Ah, I don't know much about them... didn't even know you could do that!

 

[agw_01]

Very very very nice work DreXeL

Really looking forward to seeing more progress!

 

[DreXeL]

Yeah the 'stat goes in-line before the cooler, and keeps the circuit 'closed' untill the oil hits optimum temperature. When it is at the right temp it opens and lets the oil flow through the cooler.

Make sure you prime the system before it runs by filling it with as much oil as you can.

Looks like its going well mate, nice one
