CP-e extension V6 - DONE w/ pics

[Sebas007]

Build a box around the intake to block warm air from the engine bay from entering and only channel cold air from outside the engine bay in.

Yeah good idea....I will do it even so....the air where I put the filter is 30F colder then where it was behind the battery. It was just my first step...most important was to solve my electric problem...then to put the extension. Now the heatshield/box is the next little improvement I will make.

Thanks for the hints !

What are the avantage of a oversized TB ?
Just more air so more power ??

Yea I think Paladin was the first.

One of the big things I noticed was the engine response was more linear with CPE. Before the TB I would get a big surge at 4k is is much better at low RPMs now.
Check out my post above

Hey Midias...did you upgrade your fuel system...upgrading fuel pump to walbro fuel pump after getting the oversize TB ??

[philosophicaljt]

Don't bother making the box. Buy a Used VW one. Most VW's came with one that was meant to protect the battery from the elements, but It makes for a GREAT CAI box. Just do a search on Ebay or go buy one from the dealer.

Search this number on ebay for an example of what I am talking about:
260104670407

So 130138035526 + 260104670407 = sweet CAI box. Make sense? One is the hard sturdy box, one is the cover. You really should get both.



AND



There are better boxes and such, but that is just an example. I have found it does better than any aluminum shielding I could find or make. The VW people have tons of information about that stuff. ITs worth a search or two if you want a clean look with performance gains.

Hope this helps.

IMO.

No I did not but I have been thinking of getting jims kit

[Sebas007]

Who is Jim ?? Often, I read Jim fuel upgrade...but can I see what is all about ??? Any URL ??

Thanks

isn't there access to the fender? if you can' put some more pipes together into the fender well, you'd get a lot more cooler air

Good job by the way

I'm about to say the same thing....... but too dangerous, water might get in........ yeah, good job Sebas

The temp difference between the spot I choose and in the rear fog area is not enough to start putting 2 x 90 degrees elbow and mess with the flow. The route wouldn't be optimize since it is a 3.5" pipe. 3" pipe barely go thru...like Tacti did on his I4 Solara.

Like I previously measured...

Bottom line
- More you go faster less the difference between the CP-e SRI area air temp and fog area temp is big. Same tihng with the front of battery area. The average is fu'cked because of the Test 1 at 37 MPH. Air flow is strong eliminating more hot air.

- The potential gain is always bigger in the fog area but remains way more complicated and more restrictive to reach then the front battery area.

- Front of battery area seems to have a good potential and is very easy to reach. It would surely help installing some heat shield and air deflector in the fog area (it would be a bit better).

- Relative humdity is not such a big parameter...was always the same for all the test (fog were always twice %humidity then the CP-e SRI area was)

- Thumb rule : for each 5F diff you got 1% more air dendity. 4% air density = 3% more power (hp).

http://www.hardtail.com/techtips/airdensity.html

Roughly...

Fog area temp potential give around 4.95% more power (hp)
Average of the 3 average (37, 62, 75 MPH) = 33F diff
(33/5) = 6.6% more air density
6.6/ ?? = 4/3
(6.6*3)/4 = 4.95% more power


Front battery area temp potential give around 3.75% more power (hp)
Average of the 2 average (37, 62 MPH (ignoring test 1)) = 25F diff
(25/5) = 5% more air density
5/ ?? = 4/3
(5*3)/4 = 3.75% more power


In my case I evalute I have around 240 hp
CAI in fog area could give around 12 hp at peak but would improve all the RPM band power.
240*0.0495=11.88 hp

CAI in front of the battery area could give around 9 hp at peak but would improve also all the RPM band power
240*0.0375=9 hp

Last thing to check...restriction of the CAI tubing itself. Need to get calculation of my friend engineer...but for many purpose (complexity, restriction, unfriendly install/uninstall) I think to make it like a Long SRI ! Will get colder air and be very easy to make, install and everything.

did you also try putting a sensor inside the intake where the MAF is located... doesn't matter how cool the air is... if the MAF reads same temp, then there will be no difference

[Sebas007]

If the air outside the filter is colder...I give myself a chance to get colder air inside the pipe at the sensor...don't you think ??? Especially if I put some heatshield, againt engine heat "radiation" , along the pipe.

[Midias]

in the past I have used car body undercoat spray to reduce heat on a pipe it is a thick spray on rubber coating

NICE WORK, Sebas!!!


I just caught up on the thread... great execution on the project you have been talking about for some time... (Since BEFORE the crispmongo filter idea???)

A couple thoughts I had...

- Is the only "ground" from battery to the wheel-well pan area?

(I think a lead to the engine block is a good idea, maybe?)

- Is there a 100A (or similar) fuseblock RIGHT NEAR the battery on the positive lead?

(So you won't "fry" stuff if the positive lead gets a "short" somewhere between the battery and the original positive terminal up in the front. A "dead short" on 0, 2, or 4 gage lead to the battery can create a MAJOR ARC and potentially a FIRE RISK, I would think!!!???)

Note: I see the "red switch?", but I don't know if that is a FUSED LINK or not? (Maybe I missed the comment...)

- DEFINITELY find a way to "channel/funnel" COLD AIR from in front or below the engine bay INTO the air filter area... also separating it with some kind of box or partition.

(On my "rough" CAI --> Crisp Air Intake, HA! ...on my supra, I DEFINITELY noticed a difference drawing on air from a scoop under the front right foglight... and HOT TEMPERATURE DAYS have LESS effect on my performance... and when it's COOLER, WOW! )


GREAT STUFF! Keep up the good PIONEERING work on the Solara!

[Sebas007]

Thanks Crisp...I just post stage 1 upgrade will come later this week.
for the ground issue...the ground in the trunk is really good...then thing that was messing with was the ground between frame and tranny (where the stock ground is...) I took off for the look and it's why I got problem !! I put it back (I did an other 1-gauge wire for it).

About the fuseblock link...I was thinking about it dont worry...I just hope I will not have bad luck until then...will do it next week. 100A is what you suggest me !? I read once on an other battery relocation experience that he put a fuseblock...I then realize that I didn't have one !! Will try to mess with my current setup...

About improving the cold air intake...I will do a box and put a curvy platic near the fog to route the air flow towards the filter...I think to try and other kind of filter like this one...



What do you think ?? I still dont know...

Thanks for your comment Chris and all the others !! It is all FTW !!

NICE WORK, Sebas!!!
