do you gain alot of power going with the larger turbo set up
i am bulidng up my truck to be fast now i just orders an air to air intercooler 255 fuel pump cold air kit and lots of other stuff but how much difference is there from stock to the pte set up?

i cant even begin to xplain.......

My sentiments exactly E.

As I recall this topic has been covered a 'few' times before. Might want to try the search feature of syty.net.

ok, sorry that was rude.

let me just say this.

its the single biggest improvement i have ever felt from a bolt on afair. like night and day difference. but then again, i was running a stock turbo with a mccoy motor, and it was way out side of its efficiency range.

also, you will need a TC. the PT52 doesnt like to spool below 2,500~3,000RPM. (at least thats what im seeing) id reccomend a stall speed of 2,600-3,000 the PTE stuff is made very well, everything fits great, and all exhaust is stainless. as i understand it, the 50 series turbos are also upgradable all the way up to a 63, so later when you build a motor you can just get an appropriate sized upgrade for your combo.

For guys new to this bolt on stuff visit the buick site and you'll learn a lot. I'd say anyone running a pte turbo and stall should be running very low 12's to high 11's with high boost, if you don't like high boost just keep your stock turbo. BTW: Parts are just 1/2 of the equation, the other 1/2 is getting it all to work right.

11's-------------Uhmmm????

I could be wrong, but I would think to run 11's you would need more than the PTE52, Converter, chip. I think other mods would have to be done.

Im not pissing on campfires here, just M.O. :eek:

Ive ran a 12.68@103.? and 104.? on a 45 degree day on T3 20 lbs and 110 octane. Stock turbo, 2900 stall, ultimate, icing the IC, This I thought was out of limits with the stock turbo and boost wasnt stable. I can go now and throw down consistant 12.9's and 8's with a little VHT on the track and some 1.60's 60'ft on a hi 80 to 90 degree day.

With my PTE52 I doubt I will see much more than a .6 second gain. I cant see it adding that much HP. Hopefully Im wrong and dont want to get flamed not trying to make anyone mad. I too would like to see a hi 11 but it will take a little more

:cry:

I think 11s are capable on minimum of mods, like you have listed.

Dig's buildup - built trans, stall converter, 20g, stock injectors, stock intercooler

12.0s

Tuning is the key. Daron runs 12.4s on stock turbo... get a combination, work at it, keep tuning, find out what works, what gives more power.

I admit I havent taken it to the track yet. Tuning and good healthy ignition system so and so on. 11's is alot to ask from it but I dont have the ground to speak as some of you do.

speaking of the 52, how's the 44?

speaking of the 52, how's the 44?

SPeaking about the 52, how's the 44 compare? My understanding is that it goes 20G, PTE 44, then the 52 in terms of capability, with the 44 being the biggest one you'd want to run with a stock stall (need a really open exhaust) and stock injectors (don't run much boost!).

So just for giggles here, what do you think the range is between the three turbos? i.e. *tuned properly* the 52 might be good for 11.5's, the 44 for 11.90's, and the 20g 12.0's? The stall factor might throw it all off, just trying to put things into a bit more perspective. Perhaps MPH is a better way to talk about it...

My guess would be the 20G's good for 113 in a sy, since I've seen Digs truck run 111.8, but this is freaking tweaked with great air, most guys running the 20G will see traps around 105-108, just depends on the tune and tranny, mine ran a best of 110.7 with a soft tranny.

The 44 and 52 could do a lot better, but without turning up the boost you might run as slow as a stocker or even worse, I mean the whole reason for running a bigger turbo is to run big boost and still be in its efficiency range.

BTW: I also know of a stock turbo running 118 mph in the 1/4, but this truck has a slight cam,headers, and is really freakin tweaked, I mean down to the hundredth.

Would a slightly bigger bolt-on turbo work with everything else stock? Would a 20G with a stock chip put out the same as a stock turbo, but staying at only 60% of its ability, as opposed to 80% or whatever for the stock turbo? Trying to understand exactly which things do and don't affect the operation of other things...

In other words, could you replace the stock turbo with something more efficient? Or is the stocker well within its optimum range at stock boost levels, and the only benefit of any turbo upgrade is the ability to run more boost without getting really inefficient? Or would you have to recalibrate everything to work with a turbo of different efficiency?

I'm 80 percent sure you'd go backwards, but if you added a stall I think you'd pick a few tenths even with the stock chip, the stall should cancel out the low end lag and you'd gain some flow thru the larger housing gaining on the high end. In my option its not worth it until you crank up the boost though, now if you look at trucks like Krises and Daron's the're running in the 105-106 range and then look at Digs truck which is in the 110-112 range, a little more boost and a 20G goes a long ways.
