I'm about to take the leap in to the crank pulley upgrade and was wonderin how many of u with 180 and higher daily drive your rides? Any issues with daily driving?

 

178mm here...close enough. The only difference, negatively speaking, I felt was harsher supercharger engagement, that's it.

 

I'm running a 185 on the crank plus a smaller SC pulley. You'll need some good cooling to keep the IAT's in check with that Texas climate, other then that the SC engagement is pretty sweet

 

I'm running with a 180mm and it is fine. As PACougar mentioned, you should definitely upgrade your cooling.

 

Whatever you do, dont go with RTR (Red tooth racing)

 

Same for me. I daily drive my SL all summer long. I kind of like the more harsh engagement. Its as if the car is telling me the warp drive is now on line.

 

I just tell people it's a 6 speed.

 

I have ran a 180mm plus for years now on the street/track. Put 34,000 miles using 180 and 185mm pulley`s over the years. On my new forged motor, will be running a 185mm RTR with UPD SC pulley combo and that is close to 200mm at the crank for my daily driver / part time track car. Only about 4-5 of us pushing these limits though.

 

That's a classic and I'm stealing it from you.

Been running the 180 since I bought the car so I don't know what life was without it nor do I want to know.

 

I have a 178 but in all honesty I think I would prefer a 168. The 180 just makes to much heat and kills performance for any kind of long pull most of the year for me. For a quick burst through 1 gear it is fine but more than that you can feel the power loss as the car goes flat when it is hot out. It also makes to much torque for the tires to even come close to keeping traction at low speeds so you are fighting the traction control trying to accelerate hard from a stop/slow roll or going sideways with it off so you have no benefit there.

It is pretty sad that my car has trapped 120mph when it was 60 degrees but when I went to the track on a day around 90 and high humidity I could only run mostly 112 with two 114mph runs. That is a HUGE loss in performance and I have a CM30 pump and Eurocharged heat exchanger as well as a little seperated coolant tank, so "you just need cooling" can't be said. I mean there are guys with all the bolt ons that have ran over 120 with the 168 and even the stock pulley for that matter.

If you are in any kind of climate that actually has hot weather and for a prolonged timed out of the year to compound that, it just isn't worth for a daily driver to have the 180. Doing dyno pulls you can see the power loss that you will basically see on the street, so having the the big pulley does you no good after one gear pull, for example I can lose 30+ wheel hp from a cool run to a run where the car is actually warm like it would be out driving so any extra that 180 would give you, you probably just lose and could have more consistent power with a smaller pulley.

That 180 or bigger comes in handy strickly for a car that is gonna sit in a parking lot for 45 minutes and get cold with ice on it, then have ice flowing through a tank going to the intercooler and have one single glory run then be back where it started again sitting with ice on it again. This is obviously not realistic for a "daily driver" since you aren't going to be doing that driving around. So in my opinion that performance you are seeing from some car with a 180 at the track doing all the mentioned above is giving people a false impression of what to expect with a 180 unless they have an improved intercooler for the supercharger (not talking about the heat exchanger in bumper).

Those are my $.02, take it for what it is worth.

 

This.. Looks like he is in TX too, so heat is an issue.. This car can trap over 120 with just headers and tune..

 

I agree, it just depends on how far you want to go with cooling mods. If you're looking for basic upgrades plus 180+ pulley then you probably are wasting your time. However add a Killer Chiller and Methanol and you have a all the time rocket ship, but most people don't want to got that far.

 

Water/methanol injection would be amazing if people could get it to work properly. It just seems like so few have while others get it in and then take it out and sell it since their car ends up slower losing power from a rich a/f mix. It is definitely pretty crazy the difference you feel going from a 40* night during winter to now in the summer with temps hitting 90+, so cool intake temps all the time would make the car just so much better than it already is. I suppose more people need to start going the killer chiller route and one of these days maybe a reasonable intercooler solution will come to life.

 

I've been driving daily with my 180mm pulley and everything has been fine thus far. Where I live in Southern California, it rarely gets above 90F and with my cooling mods under WOT I barely get over 58-60C. My temps crusing stay around 36-38C and on really hot days I might see 45C. I beat the hell out of my car the other night and I couldnt break 57C so I'm very happy with my setup. I am probably going to add a trunk cooler just so I can sustain 15+lbs of boost.

 

This guy above has a 180 volcano jamming boost into his engine and said he beat the hell out of his car and didn't see over 134f?

Was it 35 degree's out ? I call bs endless you are running a chiller and methanold injection or your looking at coolant temp before you car is fully warmed up.

180s will break 175 intake temps with ease if its over 80 out

 

On a 150+mph run maybe, but he didn't specify how he did his runs...in my car I can do a 0-120mph run and maybe touch 160* in 85* temps. In a 40mph to 100mph sprint though I rarely go over 135*.

Heck, the other day I went from 40-100mph in 100* weather and I didn't touch 140* intake temps.

 

Gtr are you talking about a cold car? I see 15-25 above ambient just driving off boosy .

So in 100d weather I would see 115-120 without even getting on boost!

 

No, not cold...20-30 minutes into driving. I only see 10* above ambient when cruising. If I'm stopped it'll go to maybe 15-20* over but as soon as I roll it'll go back down.

I'm running an EC heat exchanger and nearly pure water ( just a small amount of coolant for protection ). My pump is also always on ( apparently on some cars it's not but on mine it's always on ).

 

No, not cold...20-30 minutes into driving. I only see 10* above ambient when cruising. If I'm stopped it'll go to maybe 15-20* over but as soon as I roll it'll go back down.

BTW- I said I don't touch 140 and looking back I did, it was 142* to be specific.

 

I also have a modded thermostat and coolant temps rarely go over 190*.

 

188mm here and I see 10* over ambient with my standard trunk tank, heat exchanger and modded intercooler setup.

The engagement is viscous though, but then again so is the TQ

 

Out of curiousity why are you guys even mentioning what you see for intake temps while "cruising?" The supercharger isn't engaged if you are cruising and it wouldn't matter if you have a 500mm pulley on the crank, you aren't building boost and creating heat. The drastic increase in temps when the car goes through a multiple gear pull is what sucks and since the car pulls timing at I believe 120*.

 

skratch started it....lol

 

So if Skratch jumped off a bridge you would too?

 

30 shots of dry nos thru the ic do wonder, so i've heard.
