Ram Air Spooling

[Aeroking]

Just a random thought. If i fabricate a true ram air intake for my truck will it cause the turbo to spool up faster??. I dont mean a cold air kit into the fender, or an exposed K&N under the hood, but a 90elbow down outta the turbo, and a ram air box infront of the pass. side tire. Do ram air kits cause faster spooling??

Re: Ram Air Spooling

I seriously doubt any ram air effect would be felt on a turbo spinning at 110,000 rpm.

Just get another smaller turbo and run them sequential.

It like visiting the bathroom to reduce weight before a race. Yes, it is a positive step, but its probably too small to notice.

Re: Ram Air Spooling

Isn't turbo spooling because of exhaust flow. Now letting it suck in the air easier can't hurt.

yes... that is why im going to two(2) intakes when I do my A2A

Re: Ram Air Spooling

I have the Kenne Belle Ram Air setup on my SY. I think the main purpose with the kit is to get cooler air from outside of the vehicle directly in, instead of drawing hot air in from under the hood.

Re: Ram Air Spooling

I may fab a hood w/ ram scoops to cool the intake.
This would have helped tremendously on the stock set up w/ the old water intercooler.
Or maybe an Evo style hood w/ the mid section exposed for heat dissapation.
Yes, heat soak sucks.
As for the pinwheel effect on the compressor impeller, I doubt it.
Youd probably have to have an exposed turbo stickin out the hood, and haulin ass.
Even then the exhaust turbine is still smaller, w/ a faster spool. Just some thoughts.

Re: Ram Air Spooling

This is NOT true. I have the Ram air deal on my turck and noticed nothing even in the top end. It s just louder and THATS IT.

Re: Ram Air Spooling

Here what you need to send all that air up to your ram air filter kit.

Re: Ram Air Spooling

As far as I know, ram air will have little effect, someone else can do the research on the logistics. Its supposed to use the velocity of the car to create at forced induction type situation. I believe on an N/A car you need to go something like 200+ mph to get the effect on 1lb of boost...

But i couldbe wrong, I have no problem being corrected and educated

Re: Ram Air Spooling

So basically there is no way to increase spooling, by way of the intake impeller.. (at least noticable increase)

Lloyd, those would make some sick tailpipes.

Re: Ram Air Spooling

best way to increase spooling might be to decrease back pressure

They were part of the ram air setup on 1968 Hurst/Olds, 1968 and 1969 Oldsmobile W-31 and 442 W-30 cars. If I remember right, the ram air reduce 1/4 mile time by 4/10th of a sec. A tuned 1968 H/O would run mid 12 sec and the 442 W-30 tuned would run 12.8, I have the information pack away with all my other old stuff.

gotta love those red fenderwells !!!

hmmm... wonder if it'll beat a 69 428??

Re: Ram Air Spooling

to avoid any confusion, i was referring to the scoops directing air across the tops of the intake and i.c.

Lemme spin you a story....


This was about 5-6 years ago.... I had put the Sy away for the winter, but had done a couple DM runs (and had the track timeslips to corroborate 'em) the previous season.

Upon doing some pulls in the spring, I found I was .4 off my times. Repeatably.
Same chip, same gas, same road. Roughly the same environmental conditions.

Started to trace the problem... what had I done before storage? Only thing I could come up with is that I put the front cover of the stock airbox on. (I normally run the stock box with the K&N tie-strapped in; no cover). I didn't think that could be a big problem, but I pulled it just as a lark. Bam! my .4 was back. Put the cover back on, lost it. Take it off, gained it.

Did some deeper research, and where most of it came was in how the 20g spooled. The boost needle moved slow with the cover on, but shot up with it off.

Draw your own conclusions, but I won't underestimate an intake restriction again....

Re: Ram Air Spooling

Do you guys think that something like this will help with cooling down the air around the air intake?

I know it wont fit exactly but if it was able to be fabricated on the passenger side with this setup and atleast get some cool air there.Is it worth it?

i will have this setup.

what do you think?I saw someone kind of made a custom one out of fiberglass but it was a pic from the outside and was hard to see.

Re: Ram Air Spooling

Well getting rid of restriction is not the same as "ram air". cold air helps but your not going to get any gains in spooling or hp by a "scoop" or anything other than colder air. no filter, and no obstructions between cold air and your inlet on your turbo is the best, however dangerous for the turbo blades.

Re: Ram Air Spooling

You will ABSOLUTELY gain from ram air into the turbo. On my old Sy, I made up a ram air deal for the track only. There was no filter, just a ram air pipe right into the turbo. I used a stock headlight bucket, and welded a 2.5" 90degree mandrell bend on the back of it. So at the track, I would just take the headlight out quick, and put this in, in it's place. The stock elbow hose that normally goes to the crossover tube, went right onto the back of the mandrell bent pipe. So it was straight ram air, right into the turbo.

I made 3 runs without that piece install. All 3 runs were 13.2-13.1 @ 103-104mph. I put that piece on quick, which took less than 5 minutes, and made 3 more runs, all of them were 13.06-13.03 @ 107. Nothing else on the truck was changed, NOTHING.

So yes, you will pick up some power with a ram air. Obviously, mine was for the track only, but I think the debate here is whether or not you'd gain anything......the answer is yes.
