does anyone have this pulley yet from LET? if not when is it expected? im gettin anxious as to what pulley im going to buy for spring.

 

I believe someone is putting this on there car.
I too am waiting for his response as I am planning on stepping up in size to this but based on there response first.

 

Here is the thread https://www.crossfireforum.org/forum...ad.php?t=19722 that talks about the LET pulleys.

Lots of good information on page 2 (Erick from LET posted some info).

As far as I know, there hasn't been an update on the 185 install from BrianBrave.

 

It's been an interesting 9 weeks since I ordered/paid for the 185mm pulley - (part of a pulley, SL55 Intake, iridium spark plug purchase)

I spoke with Erick yesterday all I can say is stand by - I have given him a little more time to make delivery. I know the holiday period can sometimes slow production down.

I will say that Erick always offered to exchange the 185mm with the 181mm or the 178mm pulley if I have a fuel delivery issue at WOT. I am willing to take a lttle risk and be the guinea pig as my SRT-6 is not my daily driver.

I can always put my stock pulleys back on and exchange for a pulley with less boost.

Stand by!! I am just as anxious and will let you all know how it works out.

 

im thinking of the 185 opposed to smaller because i want an 11sec street car on street tires that i can drive daily. with chi-town at 12.2 with asp pulley i was thinking if with the little bit more boost with the 185 it would be possible but then the reliablility comes to question. opinions on the reliablility with the 185 pulley? i know its hard to know without any installed

 

From reading as long as you get the ecu tune...why wouldn't it be the way to go?

 

i know, i want the 185 just i am anxious as there has been a break in the cold weather and want to get the mods on now lol. I am hoping the 185 will be out for march 1st, which is when i plan on having everything on order to have the car ready for april weather.

 

I would think that even if fuel delivery is a problem at WOT with the 185mm pulley, wouldn't swapping in larger injectors solve that problem? That's all I had to do with my '00 Lightning. With my '04 lightning, all I would have needed to do was add a "Boost-a-pump" module from Kenne Bell superchargers to get more fuel.

What size injectors are stock on the SRT-6?

 

Good question. Because if wot boost with 185mm pulley is going to need more fuel than the stock injectors can support you would want to buy bigger ones BEFORE tuning you car on the dyno. Not sure if you could do a simple exchange ecu with larger injectors comming into play or if the factory ecu can even be properly tuned with larger injectors.

MBworld guys? HDDP? Anyone?

 

The injectors and fuel pump apparently are not the limiting factor.

Read this thread regarding injectors and lack of fuel with 185mm pulley:

Am I reading that thread wrong but if we don't run headers we can run the 185 pulley???

 

That is pretty much what he is saying, from what I can tell.

I guess the headers allow more our out, so more can come in (more efficient engine). The additional air the headers allow in causes a lean condition?

Now the question is whether or not the C32 that Erick used the 185mm pulley on had headers or not.

I am just shooting my mouth off here because I am no car expert; but I have some opinions to express. Whether these views are correct or not time will tell. My concern is pushing too much horse power onto these SRT6 engines will cause these engines to fail. Something is going to break here eventually. These engines were not meant to take all the torque everyone seems to want to push down it's throat. It is fine if you are a professional drag racer or nascar racer and you have lots of money to replace blown engines. But does the average owner on this forum really want to take such a chance to pay for a blown engine if you exceed the engine's limits? These engines are going to be real expensive to fix if anything has to be replaced. The other concern is how much faster you are going to go by adding just a few more horse power with these pulleys. That is to say the extra speed is not linear or proportional to the added horse power once you get to the 12 second 1/4 mile area. It is more like exponential horse power needed to get just a few tenths of a second faster. I am not saying it is not possible to break 12 seconds but it might be a lot harder than you think. Just some of my thoughts on the subject. I think I read recently in one of the popular car magazines that the new 2008 Vet with 650 hp does the quarter mile in the high 11 seconds. Welcome replies.

 

A BONE STOCK 2007 Z06 vette ran a 10.98 @13x.xx a few weeks ago in So Cal. and was verified by the track employees to be legit. That car "only" has 500 horsepower. Track number depend greatly on driver skill, track conditions/prep and altitude/temperature.

 

As I stated in my first post I am not debating whether the SRT6 can break into the 11 second range. The question concerns whether it is worth risking damaging an engine to go that fast. I think if you want a 500hp engine then buy one instead of blowing up a perfectly well designed engine that has it's limits. I am not against modifying it with something similar to CHI-TOWN ; but even he said he was not interested to go further. And I do know he is now trying to sell his car.

 

I'm not an average owner and if my engine fails then I will spend the big $$ and have it built totally race. My money My car. But these engine from AMG are stout; I have no doubt about that - it's the tranny and rear axle I am more concerned with.

It's not so much the 1/4 mile speed or time but the pull off the line I am looking for - I doubt I will track my car other then to document my times for the forum and for my curiosity. I might get the bug and go road racing but I'm not sure this would be the car. I just want my SRT to pull hard when I step on it. If you had access to all the canyon roads as I do - you would understand.

 

Sometimes it's ok to color outside the lines. My SRT-8 had 425hp when I bought it and now has rite arount 540hp. The motor from the dealer is around $10k+ to replace and I didn't think twice about its reliability when adding 115hp. It was my daily driver for a little over a year until I recently purchased the SRT-6. Engines are built to much higher standards today as compared to just 10 years ago and a AMG s/c motor is not something to be afraid of quality wise. Do you know what "SRT" stands for? It stands for Street and RACING Technology.............these cars were built to be rode hard and put away wet.

 

lol with the exception of the srt-4 with it's brass parts in the transmission, sychros goin out often, other misc transmission problems and the other mess of problems they have. (I never had any problems with my old one but all my friends with them did.) it was built to be rode hard and put away broken lol j/k ... seriously though I wouldn't go by the "SRT" (since "racing" supposedly voids the warranty lol) but I would think the AMG engine would be pretty stout. .... does anybody know if we have forged pistons, rods, or crank?.... I bet the limiting factor will be in the rear end, axles, maybe tranny?? and I have heard of people putting too small of a pulley on cobras, overworking the s/c, and ruining it. Not sure how far our s/c can be pushed.... also has anybody ported our s/c... I know cobra owners are getting a lot of hp out of good port jobs... ok that's my random thoughts... later

 

I went from a drag boat to my SRT I averaged one motor a year for six years with the boat.

So I guess I am used to breaking things...even had to pull the boat with the wife in it for a mile and 1/2 once when I blew it up, swimming with a line in my hand....At least now I can call someone to tow me

Oh and by the way I have a pulley kit installed and am looking to go bigger

 

Im not the slightest bit worried about the internals at this point. Stock honda civics can put 350 to the wheels on stock internals without exploding, srt-4's can do 400+, so im pretty sure these motors can handle 425-450 before you even remotely have to start worrying. Id say the single most important factor like any modded forced induction car...is the tune.

I too am curious how much further we can push the s/c, and still keep it reliable for us daily drivers.
