More insignificant differences between the HKS EL and Gruppe S UEL

DaiTT500 · 08-18-2015, 11:51 PM

FYI, I am on Tomei Equal Length header.

how did you like them so far? any coating? I was really going between that and the HKS EL header then I pulled on the HKS since the price was good and Bob from Drift Office recommended it.. if it ever gives me an issue, Tomei will be the next option

Both the ones you've listed are purely cosmetic.

how about the front splitter? i have got this:

with the race upgrade:

is it any benefit with the rear wing? i found it a bit heavy, but i could fit it if this would help, what do you think?

you left me in deep confusion now!

im not sure if i go for UEL or EL tomei headers! for sure i will not go with E85 and will be normal RON98, so maybe the EL is wiser!?

sorry for asking, but how to set it to zero?

you mean keep the angle at zero? the GT250 comes normal with some small angle even if you try to set it to zero, right?.

It is easy on the GT-250 since it is a 2D wing. Just set the car on a level surface and then put a level on the wing from front to back and change the holes till it is at zero. If you feel you need more rear downforce, then you start raising the rear of the wing to add AoA.

Velox Motorsports did some CFD analysis of their diffuser plus the race splitter.

Together they add a significant amount of downforce.

I say go with whichever makes you happier to hear, just remember to get a Grimmspeed gasket set or something similar. Tracking will burn up stock gaskets.

I like the tomei header. Held up great so far. I don't know how much of a difference it gained because I added the Jackson Racing Supercharger at the same time.

You had the kraftwerks supercharger, right? How is it? Any problems or complaints?

Icanfaptothis86 · 08-19-2015, 11:13 AM

UEL have no business on the race track. They sound great but the ultimate benefits of EL make it a no brainer for competitive race applications. Not sure why even debate.

Please note I do much prefer the sound of UEL but once I start tracking my car (when my current track car explodes) I will be moving to EL

Yes, I have been running Kraftwerks so far so good , except the couple cracked headers and a broken belt (my mistake on that when adjusting the tension)

I should've done the same (aftermarket header) from the beginning , oh well

What kind of cooling mods have you been using with the JR kit? Have you been logging at the track?

Turdinator · 08-28-2015, 01:51 AM

Forget the Ecutek and go with a Motec M150 with tuner local to you.
