Has any one has compare those 2 turbo the precision 4272 & comp 7288 or who's running them ??

 

Comp ftw. And you don't have to pay air arm for it

 

No **** 88 view and no one has use then or have any info

 

Try it and provide some feedback. Not gonna know unless you try.

 

Garrett GTX4502R

 

X2 since the 7280 is not available anymore.

 

How much more you can make on the 4502 over 4202? Percentage wise.

 

we had a car with a GTX4502 at etown ran 9.19 switch to Comp 7285 and went 9.09 same boost, same 60ft, 330ft and same size exhaust housing.

 

9.20 @ 163 Q1
9.13 @ 166 Q2

Sunday
9.19 @ 167 Q3
9.22 @ 166 R1
9.09 @ 170.99 R2
9.10 @ 168 going away R3

 

Garrett GTX4502R here and works great went 9.03 on a pte 7285 switch the turbo only last year and went 8.87 first full pass. This year we have gone 8.72@178 should get a little quicker.

One statement i have heard about the comparison in question is "at the same duty cycle the comp made 5 less pounds of boost" just food for thought

 

Just to add we have a customer with a 2450lb integra that went 166mph with a stock tranny on a 7275 pte.

Also my car and his car are both on gas still no e85

 

I went 8.97@166 on the 4272 PTE and we haven't had much time on the 7280. All though I ran 173mph on 7280 with more in it. From what I see the 7280 is a much better turbo, but look at Ricky's mph 178 on similar turbo.

 

Im running the 4272 Precision now on my 3rd pass i went 9.3@162 on 32psi stock gsr tranny wit a LS fd (4.2).... Gonna turn the boost up next event.... The GTX4502 should be a nice upgrade if i can get my paws on 1...

 

I did some testing with the 4502r and the Cast Borg Warner out performed it. I went faster with BW on a lot less boost. I had to run a lot of boost with the 4502r. To run 169mph on the 4502R I was at 45psi with the BW I went 169mph on less then 35psi plus BW being $1000+ cheaper .....

 

Pro1 runs the new 72mm BW and it's been 130-135 in the 1/8th multiple times

Once I get my setup dialed in to make full use of my S467 (and decide I need more) I'll probably go with the 72mm BW unit.

 

CCC Racing PTE6785 8.91@170 173MPH ON GAS! all day long......wait for the results on FTW fuel


PTE7285 = 185+MPH low 8 on speedfactory and Miller


Sheepy PTE7285 SFWD @2700lbs 8.70@179....would be nice to get the GTX turbo at same weight and see what it runs....wont come close!

 

LOL You sure it wasn't "magic" 7285's?

[QUOTE=E Town DSM;48809481]
8 4days u sure about that ...lol

 

[QUOTE=AROD;48809496]got more 8 second passes in one event then YOU ever for sure and prob more then Juan has in that car.

 

[QUOTE=AROD;48809496]I think there's enough 8 sec passes to have that tag. But what do I know. I'm just a border jumper with a camera

 

[QUOTE=E Town DSM;48809500]where were u last year at summer slam? how about outlaw? how about honda day? We should compare 8sec passes when we have a 72mm turbo on the car!

 

Last Honda day I won, this Past Honda day #1 qualifier and semi finals. At least im not making tire rubbing quarter panel excuses cheerleader.... We can go on if you want

 

Hey im still on a 67mm running on gas last year, winning events and not changing a motor each event!

 

Good for Juan. Juan is still on gas now who you kidding.
