ok, whatever the width is right now, my goal isn't really to increase it much, just make it even all the way across and get rid of the tapering, but I do want to grind down those hard angles to try and help the airflow and prevent less stacking. I'll be sure to not go over 15mm cause I'd really like to try and not loose any cooling, but I do want to pick up some flow.

I'm gonna try real hard to pick up some trap speed at the track.

 

I got the intake manifold back with the dual pass endplate welded up. But i am worried about the clearance of the endplate, what do you guys think?






Ive been looking it over and it might fit, but its going to be close. Just wondering if anyone has any measurements?

 

wow, looks great man. I don't think you'll have clearance issues with that. The only people I know of that have clearance issues are the ones that stick a nipple on it that sticks straight out. Should be fine. Now get that manifold on there and get some track times in.

 

i will be installing this back on the car thursday, i am going to get before and after HPtuner logs. Updates will come thursday night.

 

Good luck yo!

 

ya lets see what happens

 

cant wait to see what happens here.

 

how bout them updates?

 

not till later tonight, i have to put it on the car first.

 

sounds good, patiently waiting.

 

the anticipation is killing me....lol

 

Ok so far it appears to have made a good improvement. The dual pass fit fine and was hooked up with option b. Unfortunately i dont have any Logs because my buddies laptop died like 5 mins into the first drive. A few things right now so i cant really say for sure the results...

When i first took it out i was only seeing less than 10 PSI at wot. I think there might have been some debri stuck in a vacuum line or it could have been the light layer of oil i put on the coils so that i could get them back in easier. So at first i was kinda upset thinking i was gonna have to take everything back apart and look into the problems. After a few hard pulls the PSI started to go back up steadily. After some hard pulls and the car feeling much stronger, i am now seeing 17 PSI at the top of 3rd. I have never seen more than 15 PSI before. The car pulls much stronger and seems to hit boost alot quicker now than before. THe car instantly jumps to 15 PSI and then slowly builds to about 17 or so at around 6,000 RPMS. The supercharger also seems to be abit louder and the engine a bit throatier. Unfortunately this is going off the butt dyno and i dont have HP tuner logs to back it up. I will get those later.

But after all is said and done, i definitely think this mod was worth it. I will be going to the track next friday, so i will have numbers from there as long as the HP tuner logs dont show me with some crazy IDC. Hopefully a dyno run as well this fall. I really need some 60lb injectors and a custom tune.

Mods I have are

42lb injectors
2.9 Pulley
GM stage 2 Tune
Modified stock airbox
Dual Pass End Plate
Coolant Resevoir
Port and Polished Intake Manifold

A big thanks goes out to my buddy NGalaxyTimmyo for letting me use his Tools, Garage, and giving me a hand putting everything together.

 

sounds good, i like that the sound changed, but i would have guessed the car would make less boost?

 

he still has the stock exhaust as far as i can tell, meaning he can only move so much air.

i would thing he would make less boost as well. where exactly is the boost sensor locarted? i know it's before the laminova's.

 

Intake boost sensor is after the laminova's, so with less restriction there he should see a bit more boost. But I did not expect a 2 psi rise from this mod...
(However, the M62 blower itself should see less boost.)

Would be interresting to see your temperatures on full boost.

 

really? i thought it was before the laminovas. well then yeah, a boost increase would be kinda expected.

 

you sir are correct. I did not expect a 2 PSI raise either, i was rather shocked to see the PSI guage going up so high because i had never seen it get that high before. I will get those logs soon enough. I did expect the boost to come on much quick as it does, it doesnt build to 15 psi anymore, it just jumps right to it.

After taking it for a morning drive, i think this was a great mod. I am seeing 16 PSI at the top of 2nd now and it just pulls like a raped date. I love how hard the boost hits now, its alot less linear than before where it would slowly build. Now it just hits hard and you can feel it push you back in your seat. Its been a while since ive noticed that in my car.

 

I am not suprised that you saw a 2psi increase in boost.

I wonder what the boost level before the Laminova cores was before the port and what it is now? That would be very interesting to find out.

Im sorry if I missed it but how large did you open up the ports again?

 

i didnt have a micrometer to measure them, so i am not really sure. More so i took the smallest dremel round sanding tube and used that open up the ends and even it out. I am sure after that and all the sanding and polishing i did i prolly opened it 1-2 MM. Like i said my real goal was to make it so the ends were even with the middle in size wise. The slots are tapered, so the inside is bigger and as it goes out, they slots get smaller. But i honestly believe the biggest gains were recieved from polishing the inside. Polishing the insde allows for a smoother air flow through the intake, with a rough inside the air molecules get caught up and slow down. The air would be turbulent causing air to back up and not move as smoothly through the system.

 

Can you think of any easy/fast way to measure the boost before the cores? Without taping the IM and installing a manual boost gauge or something like that...

Edit

What about that plug on the bottom if the IM? You could tap that, get your measurements and then replace the plug when your all done.

Edit my edit

Which side of the cores is that plug on? Before or after the laminovas?

 

There is no connection there, so you have to make a measurement point somewhere after the blower.

 

there is no easy way to do that, i believe the plug is before the cores. But i am not taking the entire setup apart to get a boost reading now. Plus that plug is rather large and pressure fitted in.

 

You wouldn't have to but I could. I have to pull stock IM out anyway. hmmm

 

well, I'm glad to hear your observations from doing this. But with no logs, I'm still just waiting. I'm curious what your IAT's are now and if your A/F ratio changed at all from the added air flow. I'm also curious to see if you gain any mph at the track. Let us know once you have more info.

 

A/F ratio wouldnt change. The computer is told to make a certain A/F ratio, no matter how much air i put into the engine its going to try to maintane that A/F ratio. IATS i will get later tonight hopefully.
