Suggestion..
Take a look at a few of the other LS tech sites. There are 2 or 3 that have a huge technical section. One LS1Tech style website comes to mind that has more technical information that many people could even process.
Wander over there, and look up IAT information. Read up on how important this field is, in tuning. On the E38, E67, E36, and E40 PCM's, there is only 1 IAT field. (The Gen 5 Camaro is an E38) See how important these temps are in relation to tuning certain parameters in their proper location.
ATI Procharger, Paxton, Vortech, Kenne Bell, Magnacharger, Rotex, PSI, Eaton, Turbonetics, TTi, and Granatelli, ALL read the IAT's, post Poweradder (turbo or supercharger). This is not some "Blowhard" touting any specific blower, or discrediting any specific blower. This is mearly FACT.
No one is saying any one company is "Bad". But being as this is a
"Discussion Forum", there is nothing wrong with having a discussion regarding IAT's on different blowers. Trust me, ive been dealing with KB for many years. We have been questioned 1000's of times regarding IAT's. Some have been off the charts. So im in no way saying KB is better. I personally have battled 200* IAT's in the past on previous edition KB's, before we figured out what worked. So I will NEVER say the KB has great IAT's. Cause they dont. NO top mount supercharger does. They all are too high if you ask me..
As a tuner, we have tested virtually every road going supercharger. To include the new Edelbrock, and Whipple. Both, which I might add are very nice systems. Almost every supercharger, has IAT's within 10* of ambiant on the vacuum side of the blower, at the air filter/MAF (provided it is capable of accessing fresh air). Why?? Cause its ambiant.. Its nothing more than the temps you are reading from the fresh air that the car is getting. Now, lets talk about the new Procharger. Are you gonna see 10* above ambient on that one? Of course not, because the air is being pulled from above the exhaust manifold. But fortunately, they have an extremely efficient air to air intercooler that is able to pull that heat out, and get the IAT's within a very acceptable range.
Example: Say your electric intercooler pump fails. You now, no longer have ANY intercooling. Your IAT's jump to 250*. Yet your car is running around thinking you've got 85* IAT's, so its commanding 100% timing; when in reality it should be pulling 7-15*. Of course youve got an IAT vs fuel modifier that starts dumping fuel into the motor, desperately trying to cool itself off, and slow the flame speed down; but its STILL commanding full timing. As I said, you have ZERO control. If you had that EXACT scenario, with the "Post Blower" IAT's, the PCM would see the spike, and it would start to pull timing. If it didnt come down, the spark would be so low, and the fuel so rich, that your motor would be completely safe. It would only make 50% of its power, but it would be COMPLETELY safe.
Boost generates heat. Its not a myth. It is a fact. A fact that every supercharger company on the planet has had to battle.
Again, nothing is being said bad, mean, vindictive, or bias, about anyone. This is mearly a discussion regarding IAT's
FWIW, GM reads the IAT's post blower on the ZR1, and the CTS-V. They will also read post blower on the supercharged Z28.
P.S. Unpaid blowhards, are still blowhards..
At least the "Paid" blowhard is a money wh**e. Whereas the "Unpaid" blowhard, is just a loud mouth S!*t..
Just kidding around.
