Note how the inlet and outlets are staggered. The inlet is at the top of the cooler and the outlet is at the bottom. This design will force the air to flow through the whole cooler, not just straight across as if both inlet and outlets were on the top.



Also note the radiator shroud tabs at the bottom of the cooler.

  • Stock system has an accordion hose at the inlet. This hose will create turbulence because of the ribbed design.
    • ETS Solution- Extend the inlet tube to reach the stock turbo outlet pipe and use a straight, smooth silicone coupler.
  • 90deg bend at the intercooler outlet is restrictive to flow.
    • ETS Solution- Split the sharp 90deg bend up into a 60deg and a 30deg bend. This still makes a 90deg turn, but is not as sharp as the stock 90deg hose. This allows for better airflow post intercooler.
  • Plastic Pipe has restrictive dimples protruding into the airstream.
    • ETS Solution- Use a Stainless Steel mandrel bent pipe that is uniform inner diameter throughout it's length improves flow as well.



Analysis of Stock Intercooler,

Base Test on a stage 1 vehicle at 12psi shows good power, but a flat spot in the mid range power between 5000-5700rpm is likely due to the rapidly rising outlet temps of the inefficient stock intercooler. Based upon the 100deg mid pull temps, and the 125deg end of pull temp, there is definitely room for improvement over the stock intercooler.

Analysis of ETS Intercooler,

Upon installation of the ETS Intercooler Kit, the car shows a 21.05hp increase and makes 361 peak hp. Outlet temps are only 59deg at mid pull and the temps only rise to 66deg at the end of the run. These temps are signifigantly lower than stock, and it is no surprise that there is a substancial power increase with the intercooler kit installed. Aside from the midrange, we also noticed a slight Increase in top end power as well. This can be attributed in part to the ETS Replacement Charge Pipe which replaces the plastic stock pipe with the 2 restrictve dimples that protrude into the flow area of the pipe.

Through Gears Test


As our test car was an automatic, it was a perfect candidate for a pull through all 4 gears.This is the test that really shows the difference in the ETS Kit vs. the stock intercooler as this test will put a lot of heat into the system in 1st and 2nd gears, which should show the stock units shortcomings as it gets to the high load areas of 3rd and 4th gear.

In this test we see both intercoolers start out at 50deg, by the top of second gear the ETS intercooler is only up to 57deg, while the stock unit is already at 78deg. By the time we get to the top of third gear, the stock cooler has heat soaked, and the charge temps are up to 124, which is way too hot to safely control knock. While the stock intercooler is struggling in 3rd gear, the ETS intercooler is handling the temps with ease, yielding a 69deg charge air temperature. As the car shifts into 4th, the stock intercooler continues to struggle to control the charge air temps, and fails miserably, ending up at 158deg, and even causing timing to be pulled enough that we see two noticeable dips in power.

The ETS intercooler on the other hand, is handling the load of 4th gear without issue, and is returning good power throughout the rest of the pull. Charge temps rise to only 91deg, and we see a max power difference of 25hp. This is a considerable improvement over the stock unit, and is a difference you can really feel in the drivers seat.

30sec. After Pull Analasys,

The above graph illustrates the how well the ETS intercooler deals with heat even after the pull. As illustrated, the ETS intercooler just never gets hot, and even 30seconds after a run through all the gears, the ETS unit is only 69deg while the stock cooler is still over 110deg. These low after pull temps are important because it means that with the ETS intercooler System you ready to make another pull, while the stock cooler is best left to cool down for at least a few minutes.

Stage 1 Race Gas

After all of the design testing was completed, we ran the car on unleaded MS109 racegas and turned up the torque table settings. The outcome was 393whp and 414tq. Not bad for a stage 1 automatic car, with just intake, intercooler, and a tune

Amazing suit for the price
Size: Large, Color: Black
So I didn't really need a suit for anything. But I've been wanting one just in case. As such, I wasn't willing to spend a lot. Yet I still wanted to look good when I wore it. This suit is amazing. I honestly would fit between a medium and a large, and with my current trend down in weight, I may buy an additional in medium(I mean, for under $100, why not?). While my shoulders have always been a little wide for what fits my waist, the large seems to accommodate even more than I need. I worry if the medium will be too tight, but that's for another day. The pants are a little long, to be expected considering I generally wear 30' pants. Easy to hem. The vest seemed a little loose, until I found the adjustment in the back. Now it is perfect. I may still need to go to a tailor for a more custom fit, but for the price it can't be beat. And I of course haven't tied a tie since I was 16, so time to relearn that. As far as quality goes, the fabric and stitching all appear to be excellent. I went with the black, as I don't particularly look great in gray, and navy out here seems more suited for church than anything else. The quality of black is excellent. The quality of the pants is good, but I will still be favoring my dress pants that already fit well. I especially love the angle of the beast cut(whatever it is called). Whether I choose the vest or not, the black contrast with all of my dress shirts is fantastic. I will include photos sometime when I'm not too self-conscious about taking selfies.

Really amazing suit that looks like a million bucks!

This is the second suit we bought by Lupurty. The first was dark navy and fit so well and looked so good that we got one in black for our son’s wedding!

Disgusted!
Size: Small, Color: Black
I’m disgusted! I ordered this for my boyfriend to wear to prom. I ordered him a small and the jacket and the vest were not smalls, they look like they were a large. All three pieces had dog or cat hair on them and the jacket had dirt stains on the inside. They were all used! And some of the stitching was coming out! I’m so glad I received it the same day I bought it, because if received it closer to prom I would have been so screwed!!! Do not buy this or buy from this brand! Terrible product!!

Dress to Impress: Sharp, Tailored Fit, Quality Material, and Sizing Tips
Size: X-Small, Color: Navy Blue, Size: X-Small, Color: Navy Blue
This review is for the LUPURTY Men's Suits Slim Fit, 3 Piece Suits for Men, 2 Buttons Solid Jacket Vest Pants, Tuxedo Set (XS navy blue and black sets). I bought the XS knowing my son's measurements were actually below the size guide for that size, but I'm glad I did because it still worked out. The suit was a bit big—especially in the pants, which were quite long, and slightly roomy in the shoulders and arms—but it still looked sharp and well put-together. The overall fit has a clean, tailored appearance despite the extra room. The material feels high-quality and the color is true to what’s shown online. I do wish the black suit came with a black or gray tie instead of blue, which didn’t quite match. The suit in the photos is the navy blue set that my son wore to his 8th grade graduation, which matched their school colors perfectly. I also included my son’s measurements to help others with sizing: Weight 114 lbs Height 5'3" Chest 30.5" Waist 29" Hip 35" Sleeve length 21.5" Shoulder 17" Inseam 29" Back length 18.5"
