My link is in post #24 showing my 4th gear run producing a 15.2 degree rise after a good heat soaking from the four previous back to back pulls.

Correct me if I am wrong: I would assume a 4th gear pull generates more heat than a 3rd gear pull as the load is greater and it takes more time to complete the run? So a third gear run would usually show less heat being produced than a 4th gear run??

Probably, but everyone had 3rd gear logs available, so for consistency that's what were using, 3 rd gear at 6k rpms for the High temp reading


If everyone wants to send me 3rd and 4th gear logs, I could arrange it all in an excel sheet for easy quick reference...

So the CXR DIY IC is pretty decent.

Appears to be up there with the Cobb and cpe units

It would be great to see the data between 3rd and 4th gear pulls. I tend to like data from a worst case scenario stand point and my testing is always done with that in mind, hence the five back to back runs using 4th gear. I would hope that our community would purposely try to make the numbers as high as possible, then I would feel like we had good data to evaluate.

You are correct. You spend more time under boost in 4th than 3rd but it only showed about a 2*F difference. Here's a comparison, back to back with 3rd and 4th gear.

CXR DIY- log starting temp 79.5, 6001 RPM in third gear temp:88.75... 9.25* RISE over a third gear pull
3rd gear

CXR DIY- log starting temp 79.9, 6002 RPM in third gear temp:90.7... 10.8* RISE over a 4th gear pull
4th gear

Treadstone TR8 less than 2 PSI at max flow, TR8L 1.5 PSI at max flow.

-Overall lenght 28"
-2.5" inlet/outlet
-750 CFM flow rate
-500 HP efficient
-Less than 2psi pressure drop at max flow

NEW ITEM, TR8LLower pressure drop TR8 intercooler. This intercooler has a less dense internal fin structure(straight fin design) than our standard TR8 and is good for higher HP applications 575HP at only 1.5psi drop. This is the intercooler that we now give in the Turbonetics 350z and G35 Turbonetics turbo kits. Core length is 2" longer @ 24". More suited for the V6 applications, were boost pressure is kept low, with higher flow rates.

thanks silver shooter. where is the temp sensor located, on the IC or in the elbow?

Do you guys think having the sensor located on the elbow show more of a CAT rise versus the sensor on the endtank?

 

[Kevin @ Wicked]

all these logs are moot unless you measure pressure drop. Just because a IC shows a lower rise in temp, doesn't mean its a better core, what if its highly restrictive? Power numbers for each would be helpful as well as the fore mentioned pressure drop. Best way to do it would be same car same dyno same day same conditions....

 

[Silver_Shooter]

I can get some data on that when I get more time with GNocides car, but from what I have seen so far there isn't a big difference in rise, fall, or soak.

This x 1000

So Kevin, when can we bring some of the GSP kitted cars to the shop and get some real results?

 

[Silver_Shooter]

Are you guys near Englishtown? I'd be up for a road trip, test and tune, and dyno.

 

[focus13st]

Cobb surgeline meet we might be able to get a Cobb and levels car on the dyno

Speaking of Englishtown. I'll be at Raceway park this sunday for the season opener. Imports vs Domestic. It would be great to have a strong ST presence there!

I'll look into that. I gotta get the snow tires off and DRs on.

If a core is highly restrictive then it will show with a dramatic rise in WGDC to hit the same boost in similar conditions. Which isn't the case with the logs of the CP-e unit, which is also showing the best resistance to heat soaking.

they are not entirely moot..we have track numbers to back up the logs.

cx has the fastest( 2nd quickest correction) 1/4 time and fastest overall mph in the quarter vs everybody period.
im sure its not because its restrictive and the fswerks tune is 40hp above everyone elses- or is it??

You can't compare track numbers (too many variables). Kevin is saying that just going off the datalog does not give you an objective understanding of intercooler performance between each brand. Unless someone measures the pressure drop along with the temps then either set of data is practically useless for comparison on their own. That is the point.

 

[GNocide]

if something is .1 or 10% more efficient than the next brand?- i dont have the dyno or science to prove and im not sure it would make that much of a performance VS money SPENT difference anyway.
so..
i go off of data logs to compare if the change made was good for the car.
i use the track numbers as a comparative performance statistic vs whats out there.(same and different brands)
i consider how much money was spent to achieve those same results.

then i conclude if the right choice was made.
and that is the best (insert your part here)
