Intercooler Decisions

[julesk_1972]

Any chance of some Dyno data

Temps in vs Temps out

for

Bar n plate vs Tube n Fin?

[Stigmata]

Would need same car to run back to back on with same ambient etc. We just did it on a diesel Landcruiser at work. There are many types of bar and plate as there are tube n fin so it wouldnt be as simple as covering them all. I have test some real junk tube n fin that are less effecient than a good bar and plate and I have tested tube and fin designs that performed better than types of bar and plate. The less weight the less thermal energy is stored or heat soaked in the cooler. There are many variables. But I would be interested, you would need two cores the same size with the same tanks.

Yep I agree to be fair on the comparison be run back to back etc etc.

Reading the comments over time, I cant recall any temp pre/post cooler data being posted.

Plenty of dyno charts, pressures, A/F ratios, torque, but no graphed intake - cooler outlet air temps.

Or fan generated wind speed, certainly effects cooling.

Or exhaust gas temps with better cooler, does it cool gas temps or make it hotter?

So many questions.................

Just in case some of you don't know. There is an xf on here running 1000 Hp running low 9's on a $200 eBay cooler. Can't be as bad as some have said.

Edit .. sorry guys thought I was in the cheapie ebay intercooler thread. Still relevant.

Will log inlet n outlet temps, ambient and boost pressure at dyno with PWR unit. Unfortunately will be later on when I logg the euro tube n fin.

There are some cheapie cores that perform quite well, you just need to know what to look for. A mate ran a cheapie on his turbo ls1 but had dramas with intake temps getting high and the ecu pulling timing, closer inspection of the cooler revealed it basically had no internal surface area. A different cooler and she made good power and went on to run 10s. That was a sub $200 cooler too

Now we talking!

I look forward to your results Jon, the data will certainly show what a cooler can do.

[Stigmata]

No probs, just waiting on tailshaft and its off to the dyno Will be interesting

Kind regards Jon

You just cant say Bar and Plate is better than Tube and Fin or vise versa as it all comes down to how the intercooler is designed all round in each type.

I'd like to see comparisons between a Stock FG Cooler, F6 Cooler, Then Proccess West and perhaps another brand which is really going to show what is happening. Without having the time or money to do this myself I can only go by how my car drove before and after, and difference is small, after multiple times being on boost the Proccess West appears to retain a little bit more power, but overall I can't notice anything major so it may be just perhaps how the ECU is tuned.

My Car goes extremely fast when it's colder I can feel all it's power feels like driving a Big V8 when cold with so much pull, but slower and less responsive when warmer by quite a bit. Thinking this was an Intercooler issue I upgraded to a big intercooler but did not do much, but the Proccess West Intercooler kit is a very good fit considering how large it is, I like the kit and components that came with it a lot, the pipes look neat and expensive and nice, not cheap and crap like others I've seen.

There is many different types of cooler core and they all work to some degree. Some are better at thermal transfer than others, unless they are all built to the same design principle of course they will all have different thermal transfer rates. What may seem like a small amount of thermal energy say 15degC between coolers can make a big diff to how the engine develops power. It would be great to see a back to back test on lots of diff coolers.

Kind regards Jon
