Oil. I don't have a temp gauge yet for water. Gauges are driving me insane right now

it's 20 degrees Celsius here and I've been driving my car pretty hard. The stillen cooler so far has done its job

thanks

Yep. I need to drain the whole system and use less antifreeze. I'll grab the GTM fans and hopefully vent the hood before next summer.

We don't get cold enough to freeze here so I run water wetter and water only.

Yeah the worst things about the stillen kit are going to be in order 1. Tune 2. Manifold/intercooler setup 3.intake/MAF sensor piping 4. Restictive offset coupler on supercharger inlet

edit: after that its just that the headunit is to small to hit 650hp on the air hungry vhr

Can you explain your 4 in layman's terms? Number 1 is obvious. Could you also go how I would correct this?

thanks

2. The stillen manifold/intercooler setup is not efficient enough and there are power gains by switching to a front mount because of the cooler iat

3. The piping after the supercharger with the mafs in it is under sized and delivers different amounts of air to both sensors, because of the smaller diameter it also will max out the maf sensors range bellow 500 hp so your car wont know how much air its getting past that

4. Because of the sharp bends it has to make the intake coupler is a significant airflow restrictor

So I can assume you guys have afr gauges and boost gauges?

thanks

I don't but am trying to figure out where to add them.

Mine are on the A-pillar. I didn't feel like ripping out the dash to replace the OEM gauges.

What gauges you got?

thanks

Living in similar temps as you, I spent about $4300 in cooling alone, not including methanol injection. This included the GTM radiator, shroud and fan upgrade, baffled oil pan, and two 19 row oil coolers with labor factored in.. a methonol injection kit is very optional. You can use it to cool your intake charge as well as tune for some extra power. It's not cheap though and the Stillen kit won't be pushing big numbers like the GTM kits.

Of all the things that is recommended, the radiator is your weak link since you have an oil cooler. We aren't saying you have to buy GTMs, (it's by far the best) but at a minimum, spending $600 for a CSF radiator. is a very good idea.

I have not had the chance to log my water temps, but even with two 19 row oil coolers, my temps have climbed up to 105℃ and that was just driving hard on the street or dyno.

Shamrock · 11-18-2013, 01:55 PM

What temperature okay? Does anyone have an AFR or boost gauge

thanks

Bart

Chuck33079 · 11-18-2013, 01:57 PM

Defi boost and innovate AFR. That's all you "need", but I still want a few more for piece of mind.
