wow he must have a lot of fun with his evo. talk about low end torque

 

Hi

Is his 3037 a HKS unit? If not, can you tell me where he got it from? Also, what psi is he running? His Hp/trq looks great. I wonder how his spool up is. From the graph he seems to be getting peak torque @ 5000rpms.

Thanks
Ben

 

IE Evo's is not a HKS 3037s. It is a Vishnu spec GT30R 3037.

 

Anyone else with experience?

Woobos what r u tuning with? and whos doing the tuning? How much boost? Pump or race gas? Try a compression test did someone work on ur timing belt? U might remember me, 2 years ago i was the one who setup the 1st dyno day at twilight performance, RED EVO, Cuban guy, with a pocketlogger, and safc its been a long time

There is no way that anyone is getting full spool on a stock evo motor with a t67 @ 300rpm's. So they know so much more than all the tuners in the US or are they using an antilag system? The t67 cars I have been in with aem ems don't make full spool, 21psi, till around 5000. So they should be able to get a gt25r to reach full spool under 3000 since the spool up on the 35r is faster than the spool up on a t67? Whatever. I love it when people post up wild facts without proof. So I gues people like David Buschur/ AMS/ RNR/ and vishnu are all doing it wrong because their 35r's are not spooling till 4800-5000 on a 2.0l. Why don't you post up a data log with engine load and engine speed so we can see some proof.

 

Hey Joel

I remember you. It has been a while!

My dyno run was done on 93 octane @ 23-24psi. I also did a leak down today. It went fine. Cylinder 3 & 4 @ 97% while cylinder 1&2 @ 96%. My timing belt is still stock so I'm not sure.

The reason behind me asking for info on spool up is because I'm not seeing 24psi on pump until 4900rpms and its really bothering me because I hear pple making full boost @ 4000RPMS.

No GT3037 or GT3076 is not going to spool up to 23-24 psi by 4000rpm on a stock engine. There are alot of people that have no damn idea what they are talking about. Only trust people that have personal experiences (i.e the turbo is on there EVO) w/ the particular turbo you are looking at.

If you are running the .87 housing, it would be a worthwhile to switch to the .73.

 

not true. IE Evo's 3037s with the .67 a/r does. Ive been in the car, and personally witnessed it.

 

Not in 3rd gear.

My car rips off like an animal in 3rd gear at 4000rpm, but it still doesn't reach 23psi until 4300rpm. A datalog or a dyno graph will show the answers.

 

Hi

Thats the whole point of this thread. I need pple with experience to come here and tell me!

Yes, I have ordered the .73 housing from HKS. I'm wondering how bad it'll hurt the top end though...i guess you can't have the best opf both worlds.

Btw, what a/r are you using????

Thanks for the response!
Ben

 

On a typical GT30R on an EVO w/ a .82 gains only about 15whp and about 300-400RPM of lag over a .63. So it should translate to be roughly the same for your turbo. Either way a .73 is the way to go.

I have a .63 on my GT3076.

 

Looking at a boost gauge and tach does not mean you witnessed it. You have to datalogg it. I thougt I was getting full boost by 4000 but when I looked at the dataloggs it was more like 4500.

 

bump...there must be a good amount of pple with real experiences!

 

Someone mentioned that tuning could spool a turbo faster... what is best for spoolup? Advancing or retarding timing? Leaner or Richer? Is it a certain combo of the two (around 13.5 AFR?) or does advancing the timing along with a leaner mixture help in general since raising EGT's would aid spoolup?

I know that anti lag retards the timing bigtime and dumps unburnt fuel into the exhaust manifold but from what I read having the mixture too rich without a real anti-lag system just hurts spool.
