Cold air Intake

[Anonymous]

With our vehicles yes, it basically has one straight from the factory. Remove the Silencer Cone as stated above for a better flow..

I actually heard dat from a few ppl to go dat route ...thanks!

Unless you have other intake mods (cams, extrude honed/ported intake, big bore butterflies, ported heads) the need for an 80mm maf is pointless on a stock sho. If you want the minimal hp increase, and the noise, just remove the silencer cone.

well yea I was actually gonna do more then just da filter of course...Underdrive pulley,60K,ported heads,Exhuast w/Y-pipe,LPM tuned chip,big bore butterflies along with the 80mm MAF ...

All that money..just get a blower and a tweecer. Then you can use a bigger MAF.

Dunno, I get between 27-30mpg on the highway with my 3.3L with just about everything. For DD duty, I'd stick with an n/a setup.

x2 on staying n/a as a dd..

Remove the entire outer fender box. That has been shown to increase HP by about 1; you'll actually lose about 1hp if you just remove the silencer cone (saxacone). Two 11mm nuts hold it in; you'll need to remove the driver side wheel and splash guard to get to it.

IIRC I didn't have to remove the wheel or splash guard to remove my fender box. I'm pretty sure I was able to get it by removing the corner light. Then I just pulled the splash guard back a little to get the box out. Not sure though. It's been a while.

Haha, anybody asking about a cold air intake on a SHO should not be talking boost for a dd.

I wouldn't mind it in the other hand.

 

[SHOtime2511]

Good point.

I have an old SHO Shop guide log that details the power gains on popular accessories. I thought I would post them again. The dyno used is a DynoJet model 248C. Its my understanding that this is the best dyno to use because you can achieve repeatable results. The car used is a '89 SHO with 111K miles. A 60K was done on the engine with a leak down test to make sure the engine was in good condition. They ran the engine stock for a baseline then ran the car again after each power mod. Here are the numbers...


Stock HP 183@5900
Stock TQ 189@2800

Added 80mm MAF w/LPM and cone filter
HP 189@5900
TQ 191@4800

Very little power gain and the tq peak moved to 4800 rpm.

wow...pullys free up that much??

 

[SHOtime2511]

Yeah I noticed a gain after pullys.

 

[32MTX]

brian what kind of pulley setup do you have? did u replace the crank pulley?

 

[xshoel93x]

prolly isnt that different on other year shos but when i took the air silencer cone out of my 93 i just unscrewed/enbolted the marker light and removed the filter and top part... reached in and pulled it out. or maybe i pushed, whatever. real easy. i dont notice a power increase, prolly isnt any, just sounds a bit different, as others have said

 

[SHOtime2511]

I kept the stock crank pully.
All the other are aluminium underdrives.

 

[SuperHO]

same here...except i've got an ATX power steering pulley and a stock alt pulley due to having a sub amp.

 

[jelloslug]

Are those numbers cumulative or are they for each mod individually?

 

[pascalman]

If you want sound and a little gain I can send you pics of a $25 CAI
