500+ Rwhp
do you think this turbo is capable of puting 500 to the ground on my 7 http://store.yahoo.com/cheapturbo/garrettto4r.html
|
it can do it
|
a/r too small for a rotary
|
what size a/r would you suggest that would be better
|
.81 or .84 ptrim might get it. .81 or .84 q will get it. The .70 with a qtrim might do it, but not sure. Problem with ptrim is I think they are all small shaft and may not
stand up to the load- not sure about this, ask around. |
sounds good I did some looking around and found some good info, I might go with .84 P trim, with a diferent turbo PT-67
|
that turbo is basically a pt67. the a/r is not to small for a rotary. i think allrotor is confused. that turbo is well suited for the rotary.
|
by the way that turbo will support WELL over 500whp on a rotary.
|
but will it give me good top end and fast spool up I'm looking to have 15 psi at about 3500 rpm if possible

TO4E & Big KahunaTO4R(second pic)
AND GT40(1st pic) . The TO4E was sized by Bell of Cartech for a 13b street port Kit...thats what kit I used to have. You can see the others are large enough. |

i believe a .70 will choke on a p trim up top. |
My question is why do people ask what it takes to get 500+ hp? Do you just want dyno numbers? Are you tracking or dragging the car? Why 500+?
400HP stock twin FD's are in the 10's. And a 400 HP FD is just raunchy on the track.. Ask Damian.. If you want 500, get a Supra. It's easier and more reliable.. |

allrotor your confusing compressor housing a/r (.70) with the turbine housing a/r
|
ok i guess ill have to prove my point.
http://www.teamfc3s.org/forum/showth...5&pagenumber=1 kabooski for florida. 479 whp 14psi......520whp 19-20psi also note the 400 plus ft lbs of torque ladies. that turbo he is using is the so called turbo that will not push 500whp: pt67,t4/to4r. he also runs a ported 13b with one of the smallest turbine husing a/r's u can get with the pt67. |
pt67: 67mm wheel, .70 comp a/r, 360 race bearing, tanged .81 a/r turbine housing, p trim
|
this turbo depending on wheel and hotside a/r will support over 700whp

thats not the point ernie. the point is that the pt67 will support well over 500 whp. she wont start singing till over 20psi of boost. like ive said before this turbo is designed for engines with airflow like 2.2 to 2.4 liter engines. i have a h22a with this same exact turbo at my shop pushing 411 to the wheels at 12psi. granted this engine is highly modifyed but it still shows u what this turbo can do with the right parts to augment it.

i thought they were saying the turbine housing was a .7...thats why i was saying that. sorry for the confusion |
well the reason for 500+ is just my goal, "If you want 500, get a Supra. It's easier and more reliable.. " the reason I dont get a supra is I don't like it, I'm a RX7 FD fan and nothing will change that but thank's for your sugestion. I whant dyno # and results at the track

I have another thought on those numbers and turbo. I also think he did the numbers he says. It's the turbo I question. He's sure it is a .81 a/r but was not sure of the wheel size ( from his original post ). He lives close to CentralFloridaTurbo and they sale S and R exhaust wheels. Could those number be more consistant with a bigger wheel?
I am thinking of upgradeing from a .96 a/r p-trim to a .96 a/r S or R wheel but if those numbers are correct for a .81 p-trim then I will not waste my money on a new turbo. chuck |
ill post here from expirience, i bought the same turbo from Ken. TO4R with .96 rear .70 front and a p wheel. I made 493 WHP at 22lb boost with 93 octane fuel and alcohol injextion.
here is the dyno sheet http://img.photobucket.com/albums/v2...0Sheets/11.jpg also, what mods u have done to the internals of the motor will determin the power outputs you will achive and for how long the motor will hold up. |
sounds good I got about the same set up with a AEM EMS thak's for the good info

I see your point. I've just not seen that high of numbers around for what I view as a small turbo. |
how is a 67mm turbo small?
seen plenty of people make 400+ on a 60-1 (60mm) at 15 PSI maybe too small is your building a purpose built street drag car a civic around here made 640 FWHP @ 28 PSI with a SC-67 (precision turbo) a couple of DSM guys have made 540+ with SC-67's also theres ALOT of people around my town that are using presicion turbos all with great results Like you stated your self Ernie its in the tuning or you forgetton blowing up all those motors to get the numbers you finnaly got with your old car............ |

Ernie T has a good point I'm looking to make about the same power all on pump gas with some alcohol injection to try and hit 600

Everyone has one as well as different goals.

exactly 400 on a FC / FB or FD would smoke a 400 Supra, mustang etc
if I wanted 600 RWHP on C-16 its only some clicks away on my boost controller but whats the use? if I can't put it to the ground T&R has a customer car that ran 11.2 with only 388 HP (has suspension and roll bar) cuts 1.56 60' foots I'm only cutting 1.67 and gets loose on me hence I'm working on my suspension and chassis now |

ernie, about the z06 pulling a rx7 if both were to have 400whp...not exactly true. Rx7 weighs less...given the same power the rx7 will win. Simple math. Local z06 with intake and full exhaust got inched by boostcrzy from a 40 mph roll to 140-150 mph...z06 was making a tad over 400whp. Boostcrzy has bolt ons and extra injectors and an intercooler., roughly 350-370whp.
|
I have a friend w/ a Z06 and I ran him w/ my red 7. He pulled me top end. Figured it was a combo of pwr and gearing in the vette.
|
Well anything can happen in a race, especially on the street...driver error etc. Im just using simple math to explain my conclusion. I think most would agree that the same given hp in a lighter car , the lighter car will win...not like rx7s dont have decent gearing to begin with..;p

btw ernie hows the car coming along?

All of those numbers on piston engines would be about 20% lower on a rotary engine. Thats basically a T66. It would be good for about 530rwhp, but barely and at around 25+psi of boost. If you want to make 500rw at a decent boost get a large port and a T72 or GT42. Thats the size you need to make that hp level at lower boost levels. BTW - When you look at a website that shows how much HP thier turbo is good for realize that the spec is for a piston engine, at the flywheel, and peak boost. Take thier HP specs, multiply times .80 to convert to rotary, then multiply that times .85 to convert to RW. That is appx what you'll make if you max the turbo. Stephen |
Something I just noticed on that turbo you linked to. Its specs say....
flow: 75 lbs/min 960cfm Well, 75lbs/min is good for about 570rwhp on a rotary. HOWEVER, 75lbs/min is 1086cfm not 960cfm. The 960cfm is only good for a hair over 500rwhp. Guess it depends on which one of thier flow specs is the real deal....if you can trust either. Stephen |
hey SPOautos thank's for the good info very helpfull for me and probably for a lot more people
|
things like flow ratings and compressor maps are not info that is set in stone. its to give the person viewing those things a basic idea of what that turbo/wheel can do at certain rpm, boost, and speeds for different engines.
lots of things effect how much power a certain size turbo will make. i.e. engine efficiency, compression, displacement, backpressure, sea level, these are only a few. the sill of your tuner will be mostly responsible for how much power your engine will make. bootm line: member who started this thread asked for a turbo that can produce 500+ whp on a rotary. pt67 can and has done it. its dyno proven. instead of kicking a dead horse how about we offer other turbochargers that can make the power level jin is asking for. |

Interesting, and I thought the PT67 was Precision Turbo....not some no name Phoenix Turbo that he is looking at from Cheapturbo.com. I have no idea if its the same or not. The specs might be similar to a PT67, however they are also similar to a standard run of the mill Garrett T66. Who know what kind of compressor wheel and CHRA they are puttin in it. You are right though, the compressor map isnt always accurate and is based around certain conditions. That being said, the compressor maps if anything are usually high, not low.....obviously cause that makes thier turbos look better haha. How could you trust them anyway? They list 2 different flow ratings for the same damn turbo right there next to eachother. They need to get thier shit together, they probably dont even know whats in thier turbo. Stephen |
just a question for ernie. whats your best Qmile time
|
well stephen thats why i never buy turbos from "some place on the web". when i buy turbochargers for clients i go right to the source for selection.
http://www.precisionturbo.net/turboc...tegory_id=3027 i like going to shops that specialize in forced induction. not some website on the net. usually the selection is much better. IMO precision and innovative are awesome turbochrgers the t4/to4r they sell is very similar to the pt67. is it the same quality? that i cant say. for now id stick to the precision stuff. |
jus my 2 cents, congrats to kaboooooski for making the number!!! what ever "boost" it was at it was made and still alive (i think) as for my setup
i run a PT 74 GTS this turbo kicks ASSSSS.the problem is it moves alot of air your probably thinking this is a good thing,and it would be if you have the correct fuel system ems etc.......I tuned the car on a dynojet about 2 weeks ago and made 560 @ 28 psi w/ a/f @ 11.2 .............long story short took it to track to break the 10 sec ROAD BLOCK and insted blew the engine :dragster: and ran a 11.2 @ 120mph cuz I kept my foot in it. the moral to ALL this is making the power is fairly easy keeping it alive is another topic my turbo picks are TE-44 (made 400 rwhp) .58 street 64-E (made 480 rwhp) .58 street .81 race 74-GTS (made 560 rwhp).81 E nuf ALL are PT turbos!!!!! |
Nice to see Tearbo2 is still alive.
Those are some nice numbers Tearbo2. I can see those number with a S-trim wheel on a 13B. Makes me wonder about making over 500wrhp with a .81 p-trim wheel at only 20psi. I pushed my .96 p-trim pretty hard and was seeing boost drop above 22psi. I always thought it was the exhaust wheel/a/r creating to much back pressure. Could be totaly wrong about the smaller a/r and p-trim wheel not able to support over 500wrhp without pushing it over 25psi. Tearbo2, I am looking at getting a PT72 .96 a/r with a S wheel also. Now seeing your numbers I think I will get it. Was starting to think it was to big. chuck |
