Well I think thats obvious... I can't find any PE compressor charts online. I'll have to look for mine when I get home. But I did find that the major diameter of the PE1420 is 60mm. Thats roughly equivalent to a T3 compressor wheel major diameter (Garrett, Turbonetics, Precision, etc). Assuming the highest flowing T3 available (T3 Super 60) The max flow rate is in the neighborhood of 35-37lb/min. That should net you roughly 700-750 HP of air assuming good efficiency. That being said the pressure ratio to make that is roughly 2.60 (23 PSI) assuming ambient pressure of 14.7 PSI. At that pressure ratio the turbo should be in its last band of efficiency if not completely off the island. Like I said could it be done absolutely and clearly it has. BUT a larger compressor would be better suited if those are the plans. That was my only point in my comment. The cars make power and run great times. But there are better ways to do things and I'm pretty sure this board is supposed to be all about finding the right or better way to do things.

 

Not 1 person said the turbo's woudlnt make good power-regardless of size. Sharif simply expressed his opinion on what they could do(550whp), one person questioned that and you come in with something that proves nothing in this particular post. You having a tough day or what?

 

Conservatively 550whp. Like you mentioned, you never really know until you try. And smaller frame turbos have sometimes surprised us with their power potential.

 

I think part of the problem on right or better way to do things will vary between owners due to different performance characteristics desired. No one turbo kit, TT or single, will ever be "best" because it will never be all things to all people. An attempt to make the maxium possible hp on the VQ, without any other consideration except that, would most likely entail a custom kit. If you observe the high hp number cars, they have various deviations from the standard kits, everything from wastegates injectors emu fuel systems etc, new intercoolers, on and on. That is what makes this board and the exchange of information so valueable, so we can see what works and what doesn't.

 

hoefully soon we can just figure out the potential when i come up there sharif and then we can post up what we get and that should help settle things

 

I agree. I just wanted to point a potential limitation of that particular turbo. In fact I believe PE was planning or has released an upgraded turbo for those wanting more power. I think Cheston has them or is getting them. Just making the observation thats all. I'm not telling anyone to get another kit but more so that they should look into larger turbos if their goal reachs beyond 550-600 as those turbos should be close to or past their limits at those power levels.

 

I was actually replying to Mias post you troll, no like I said, stop harrasing me please..

 

I still never said the turbos wouldn't make power. I just said they might be out of their efficiency at that pressure ratio. Sure the turbos might still make power there but a larger PE turbo might make BETTER power at the same pressure ratio. Thats all I'm saying.

 

Julian the name calling is very professional bud way to rep MRC Im not harrassing you if I was Id be calling you names and Im not....

 

And i agree...They are good for about 550 whp..anything past that, their blowing hot air..Please ignore Albertos posts, he has a gripe with me and stalks my posts and plays word games with me..Sorry for the confusion.

 

please leave me alone..this is the last time i will ask..

 

You are the most childish shop owner/manager/tuner I have seen. Look at all this time you spend bickering about stuff, shop not very busy I take it? And BTW-is that supposed to be a threat? Id hate for you to threaten me with your guns you carry like you did some other guy in another thread

btw-you want me to dissapear? Simply add me to your ignore list.

 

From experience, the PE Turbos are max'ed out at around 650whp - then things just get really HOT! this included head work, cams and a very free flowing exhaust… my guess is 550whp is pushing it with out the supporting mods…

I've still have mine lying around if anyone needs to see some pics... I'm running a set of Full-Race tweaked GT28RS now...

Listen guys - I've turn over a new leaf and I'm just going to flat out refuse to engage in any confrontation on the forum - I sat back and read a lot of the posts, and it's pretty childish...

Let's all just have a group hug and talk about making our cars fast...

 

Yeah how bout getting us some compressor maps on those PE1420s!!! j/k I hate it when manufacturers don't post or release compressor efficiency charts. I understand the need to be secret in terms of design but a compressor map is going to reveal THAT much info.

 

Getting parts or information out of PE is like pulling your own teeth with a pair of tweezers.

 

It seems like. Unfortunately that makes life for tuners and customers alike hell. You don't know if the turbo is going to suite your needs until you buy them and test them to find out. Of course that costs a lot money. A compressor map would tell you before you spent one dime if the compressor meets your needs.

 

I would be willing to loan out one of the turbos to a reputable person for some testing... One condition, if you break it or misplace it you buy me a new one...

 

If I had the equipment to flow test the unit I would. I'll ask around though. I haven't yet found one PE compressor map (being googling for over an hour now) You wouldn't also happen to have an APS turbo too would you It would be nice to see compressor charts for all the turbos available for the Z.

 

Sorry, no APS turbos... lol

 

mia, you mean an aps single turbo or the twins?

i have a spare aps single turbo in my garage.
