Trying to decide Heat exchanger or Tires NT05R - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

d454brisson · 03-01-2017, 11:58 AM

I just finished the Rough idle cam and am working with Ted for the next pulley tune revisions

Trying to decide whats more important now for the street as I am going to eventually get a set of 17 replicas and drag radials

Either 20 NT05R tires or the Ron davis or Afco HE?

I have read Teds thoughts that a HE isnt really needed but the forums been light so I figured I would get some thoughts before ordering tires

Where did you read Ted saying that an aftermarket heat exchanger is really needed?

Sorry typo, meant to say "isnt" really needed

Yeah that's why I asked because I've always seen him say it isn't really needed. Other opinions on here will definitely vary, though. I am kind of on the side that says it IS needed.

ZEV1L ONE · 03-01-2017, 06:13 PM

If you want the car run more efficient pull after pull, then I'd get one, not mandatory however. In my opinion, if you've got the supercharger spinning faster with a OD pulley (I.e. more heat) I think you should invest in one as well as a reservoir. If you look at the stock HX compared to an aftermarket one, night and day difference, not to mention its 10X easier to bleed the system and keep up on the proper fluid levels. Given that you have the cam and pulley already, its one of those pay to play things. Again, not mandatory, but, if it was my car, I would absolutely do that (and I did, went with AFCO)

I know Ted is of the opinion that its not necessary, but he does at least recommend an interchiller or some other option to cool the IAT's from what he's said in the past to keep a handle on the temps. At the end of the day the cooler the IAT's and the less timing pulled from heat soak, the more power... and more power is always good!

Just my .02

IMO, a HX is needed before drag radials. Drag radials tell me you want to race it or do a lot of pulls. If you were asking about a summer tire that you were in need of for a daily driver, I would say go with the tire.

I went with the AFCO and am super happy with it. I think it was $415ish shipped on ebay.

+1 for an Active Interchiller benefits have been proven time and again. I have a ZL1 customer that just removed a huge H/E with fans less than a year old in favor of going back to stock H/E and Xtreme Chiller. I got a text from him today asking about Freon Charge is 48* IAT2 90* ambient good or should he add another oz Freon. Many are going in favor of no H/E and just an Xtreme Chiller

If you want to have a few fun passes at a drag strip/street get the Nittos. They hook great on these Camaros. If you plan on staying at the track all day or doing any road racing get the heat exchanger. The Afco is a great way to go

jrhagen · 03-01-2017, 07:38 PM

It is good for road track days but other than that it is useless. I wasted the money.

d454brisson · 03-01-2017, 08:15 PM

jrhagen what did you wast mony on the HE?

Not really a daily driver but I do put some miles on it to the office on good days, local happy hours etc.

At the current power level on a 60deg day it just blew the rear tires off when I was trying to merge 2 lane to one with a gentle curve. When it finally hooked it was gone.

So my thought was the 20' nt05r with the small sidewall would be better than the stock GY on the street, while i understand not optimal at the track. Rain would be only a got caught out in it thing versus actually taking out in rain for a transportation need.

As summer comes it will see more miles on clear days to golf courses etc, track would secondary aka see what it can do, run with a few friends etc.

If i did either interchiller I would keep HE in place as I wouldn't want to deal with AC failure I could see times when I am keeping cabin cool and dont want to worry about losing that efficiency.

Based on what you're stating, I would go with the tires first...Plenty of time in the future to do upgrades for the track...

Viczl1 · 03-02-2017, 06:06 AM

I agree with Stunnah. Tires first.

robrocketanski · 03-02-2017, 06:15 AM

I did about 20 runs in a few hours. Once when there was no wait at all I did them about 6 minutes apart. You could argue that I lost a tenth but look at the 60 and you can see I lost the tenth there. The cut off one is a 10.873 with a 60 back to what it was on the 10.84 run.

There are only two arguments for the HE based on these results. Either I was already hot all the time and therefore don't lose power because power is already down or I was able to cool off enough on the return road cruise for 6 minutes. That time for a convertible is pretty good for 28% overdrive so I think I am making decent power and if 6 minutes on the return road cools it off enough then I wouldn't call it heat soak.

Just my own experience.

I will say if I had regular tires or the stock tires that would have been one shit day spinning down the track. I was on 305/45/18 MT Street R and still could spin them.

crazydave · 03-02-2017, 07:34 AM

When you sat DRs, do you mean 100% of the time or just for fun and track days? Just be aware DRs, even Nittos,affect the cornering of the car. I hate how my car handles with the DRs on the back for daily driving, they are great for straight line pulls, but they noticeably suck in the twisties on the street and the rear feels like its wandering around and not planted, due to the flexible sidewall. The great thing about this car is its really great at 1 thing, but its good at everything, so as soon as I'm done at the track the street tires go back on.

HX are great, but if you are not 1/4 mile tracking it I would save your money. The stock system for the most part can keep up as long as you are moving and not under boost alot, like 1 or 2 WOT gear pulls on the hwy. The aftermarket HXs don't do much when you are under boost, (they do help a little, maybe 5-10 deg IAT2 difference at the end of the 1/4 in my experience), but where they excel is recovery time. My IAT2s came down twice as fast on the return road at the track in comparison to the stock HX and if you are on the hwy cruising, this is not really going to be a factor.

I would advise you to just save your money unless you are serious about tracking the car.
