Well today after 2hrs of grinding and cutting its almost done 00vi with No VIAS and almost no runners. Im gonna use this for a high revving VQ35.
After

Before

 

looks mighty interesting, can't wait to see what it amounts to

 

are you going to use a modified lower intake manifold too?

 

OH nooo i hope thats not what i think it is

 

Tilley, I know you posted your track times, but do you have a dyno to compare to your old setup (you made 238whp/223wtq I think). What does the butt dyno say? Pulls harder on the topend than the 2002 manifold? What about low end?

 

someone isn't going to be happy with this

 

secret sauce?????

 

I don't think it's as effective as SR20's manifold. He was trapping 107-108 mph last I checked.

 

Only tme will tell. . . .

 

And that time will be friday night

 

Well its completed with IAC hooked up and TB adapted I will test it out today.

 

Sorry for the newbie question, but what would doing this gain you as far as power/capability? More top end? Loss at low end?

 

More topend and i higher peak, but tq loss on low end

 

i like low end

can't wait to see the results

 

Well first test drive shows it pulls all the way too 7300 im still playin around with it.

 

When are you going to dyno it?

 

Lowend sucks when you have so much of it. I hop all over the place in first and second.

What did you use to seal it back up? How did you keep it from protruding inward and restriction flow?

Is that Krismax's IM?

 

How much would you charge if I asked you to make me one?

 

i can't see certain angles so I could be wrong on this...

but doesn't cutting that out and putting that flat piece of the bottom make the runners longer? (it looks just like a 4th gen US IM now)

 

nope, it creates a second 'plenum'

 

Looks like he cut out the varible portions of the intake. So now it's a always on or always on the "open". Even more so with all the stuff out of the way.

 

I wonder if taking out the butterfly valves and and pins holding them in the MEVI would be a worthwhile 4g trick ...

 

Nice Tilley

What track you hitting friday? I might try to make it out

 

maple grove 10am-4pm (so it will be empty)

 

Great minds think alike. Or similarly, at least.

 

wow, i wish i had the time and tools to have a project car and do stuff like this! but since im such a young grasshopper ill have to wait till im old and wise Great job tilley, cant wait to see track results. Tank, hows that interior work going? Hows the max doing? We need to hit up the track here soon, now that the weather is nice. Paul and i are going to be installing my y pipe as soon as my gasket arrives! I want to see what she can run at the track.

 

well after 2 days of testing it feels great. It drops the tq (helpful with 3.5) but it pulls too 7300 (valve float). I DO NOT recomend this too anyone who has stock rev limiter or wants tq. I came to the conclusion that tq might feel better but when you got too much you can get up and going fast enough, at least at the track that is. I was launching at 6k on friday night

 

have you ever thought of making custom individual throttle bodies?

 

So ... DEK IM > 02+ VI ???

For certain application ---> high revs/race/manual tranny

 

The advantage of individual TB's diminishes when you have to enclose them in a plenum in order to draw air through the maf sensor. To get rid of the plenum you would have to go to something other than an air-flow referenced fuel management system, which complicates things.

 

i dont know you but sometime you should come up to maple grove and race. idrc is the best time because its an actual race event (and show) and its virtually empty every year. its worth the drive i promise. how far are you from mir and in which direction? it took us 3 hours to get to mir from here.... but it was worth the time and traffic on 95 and 695 lol

 

I'm sure they would sound cool

 

Your "Step 1" was a cleaner solution IMHO, but performance should be the same.

Great job Tilley....

I love it

 

OMFG! That is so sweet.

 

Thats nice....

 

Wow, that is a great idea. Looks like 4in piping

 

We need some numbers or somthing on this.... Awesome.
