Short runner manifold

[striker]

Ah S*** justin tommorow is to late, we'll be leaving 7:00am for 24h Le-Mans race in france.
(YIPPIE Beer and judd v10 powered LM P1 cars: the best combo on earth)

will check in tonight because I'm very curious about the way you mounted the fuel rails, that was my biggest brain buster, I couldn;t find a way to do it neatly so I opted to redesing the manifold/intercooler so I could fit it in its original position.

I'll see what i can do...went to tap the threads and the machinist has made the hole too large, duh. Will need to use M10 cap heads now bugger.

 

[striker]

Justin you can eaily solder them up using, durafix brazing rods. if you then tap again it's even stronger than the original cast alloy stuff of toyota manifolds.

M10 seems a bit daft.

[JustenGT8]

No time mate, caps heads will be fine....overkill for sure but a simple matter to drill out plenum holes...already done in fact

If i can just find where my little girl has hidden the digi cam i'll have a pic up soon

 

[JustenGT8]

Here it is

 

[striker]

NICE!!!

gave me an idea, thanx!

of to sleep now le-mans convoy leaves in 6 hours!

Looks good Justen, eagerly waiting for dyno results........

The stock plenum bolts on? Im sure you checked this and the picture must be deceiving, but it lookes like the left to right bore spacing looks larger then the stock speed.....

Is the height the same as stock?

 

[JustenGT8]

Yeah made for stock plenum and is pretty well stock height as well.....as straight bolt in as i could make it. Will be for sale soon if dyno results are encouraging

 

[JustenGT8]

All fitted up

 

[cjsupra90]

Justen, Fitment looks great. If the Dyno results warrent production, any idea as to pricing for the unit?

 

[JustenGT8]

Another pic of the final installation....with all the covers on etc it's even more stealth. If i went back to the stock fuel crossover you could fit the front covers as well and you'd never know the lower manifold had been modded...a plus for you smog restricted types

 

[JustenGT8]

Just got back froma road tune...holy ****,, butt dyno says big difference

Pulls strongly to 6500rpm and still feels nice and clean out to 7000rpm so i'm thinking the dyno is gonna show some great hp gains. Tune was sweet,, just needed a slight fuel pressure tweak.

Idle is still very high though so not sure what's going on there? I was pretty thorough is checking for vac leaks but guess i'll have to go over it all again.

At the same wastegate setting that gave 12 - 12.5 psi i now get 11psi so definitely some increase in flow.

So,, pretty much all good thus far

 

[V8Datto]

I'm sure like everyone else,

I'm very interested to see what the dyno shows

Awesome job

 

[RedPhoenix]

:O.... Im so curious.

 

[4000GT]

You probably do this anyway Justen, but if you have not, get a piece of tube the size of your intake connector and weld in a plate and pressure fitting to the tube, then put in in the intake connector, crank the air compressor into it, that will find any leaks you have!

 

[JustenGT8]

Yeah, was just gonna use PVC pipe i have lying a round but same idea.

 

[StiCk3]

looks really nice, can you post up the dyno graphs?

 

[spf_lexus]

it looks like an old school velocity stack. Guessing that this would kill some low/mid power? if so then it must have an insane boost for top end.

 

[Zuffen]

A velocity stack is usually longer than a normal manifold runner to get the flow right.

In this case the runner is much shorter than stock so theoretically it should produce more bottom end.

 

[JustenGT8]

Butt dyno says gains across the whole rev range.....will try to line up dyno asap.
