Razorlab - 2020 LE build thread

I just ordered the louver. Thank you again. Did he use a template or just measure and cut? The verus template sits closer to the front than the GT500 louver so I can't use that template

He measured and used cardboard first to do test fitting. I haven't done mine yet as I have other things to do first but I'm not really looking forward to cutting into the hood anyway. hahah, let me know how it goes!

Do you have a part number for those wheel well vents? Those look great

I believe those are Sayber Designs and he painted the CF black

Beautiful work! I’m just going to not track during our 6 summer months. But haven’t really tested how she’s going to handle the hotter temps down here in March. I may even push into April… Great job and build

Last piece of the winter mods arrived today. Rollbar from Dashbuilt. Slightly custom. Arrived incident free. Time to rip apart the car again!

Spring is right around the corner...

Set camber all around in prep to align. Flashed my ECU, no longer oem power! Backed out of the garage to settle the suspension and snapped a quick photo.

Is it spring yet?

Picked up tires for the season...

Have you ran the Ar-1's before? If so, I'm curious what your thoughts were on the difference between them and the CRS. I've been running the CRS for a while now and swear by them, but always open to other options for track days.

I haven't! I also love the CRS. I'll let you know!

What made you switch from the continental extreme force to these? Im debating on grabbing the conti's considering how long they last

I only used the Conti Forces for the beginning of last season. I liked them overall but I was after more grip, hence the move to the Nankang CR-S.

Swapped my OEM intake manifold for the Wagner Intake manifold. So far on the street, it looks very promising. I'll share more data once I get the car back on the track for the season.

Power mods:
Pure 700 Turbo
GESI catted downpipe
BM3 tuned (track tune)

Stock intake manifold 3rd to 6th gear WOT
55*F ambient temp
19*F intake temp increase

Wagner intake manifold 3rd to 6th gear WOT
72*F ambient temp
4*F intake temp increase

So I took a look over all my logs from yesterday and they all had 25-30F higher IAT at cruise so I thought that was odd. I thought I might still have air in the system so this morning I bled it all again and went out and grabbed more logs.

Now at cruise, before WOT, the temp is 15-18* higher than ambient, just like the stock manifold. 81F ambient today, cruise on hwy was 96F IAT. So it looks like I had air in the system yesterday. At WOT, the manifold is performing even better now!

I also logged pre-throttle intake temps this time. Makes it really clear the job the intercooler in the manifold has to do!

Single gear (4th)
Pre-throttle intake temps increase 124*F
Post manifold intercooler intake temps decrease 2*F

Multi gear (3rd-5th)
Pre-throttle intake temps increase 137*F!
Post manifold intercooler intake temps decrease 1*F

First track day with the Wagner manifold intercooler. Not perfect data as it was wet and rainy all day and about 55F ambient. That said, the intercooler is still working well. I could come in after a session and put my hand on it and it was cool to the touch. Here is about 12 laps and then zoomed in at the end of the straight of the 12th lap. Highest IAT i saw all day was 102F.

Kinda nuts that it has no problem cooling 260F pre-throttle intake temps down to 99F. 161F difference.

Also, no heat soak when I was sitting in the hot pits idling the car waiting for my session:
