i am down for a after shootout party or something ...i have my manifold and am going to shortly order my gt35r. I think i have all supporting mods and am currently flashed ....although it would be considered a old flash now since it has been in the car for quite a while. I use a s-afc2 so i can fine tune it while on the road with my wideband system. I am hoping that we can work something out interms of a flash for my application. If not then i will have to go to another setup i guess....aka ditch the s-afc2 and get a utec or aem or somthing. Anyway al , let me know via PM ...search me and you can see my car and mods although there are more mods now...

 

OMG that is the most usefull dyno graph I have seen yet. All that power and it never falls off and hits really quick. 3240 turbo is also a great turbo a bit lagy when I drove my friends evo who has one on it. But man once it hits its gone.

 

Al are you selling your old set up?

 

Al, can I offer a suggestion? What about a prostock style system, a launch control with a "soft" limiter that allows you to peg the pedal, run it to the limiter making as much boost, dumping the clutch in the process. I know prostock cars have used this and it can't be electronic, making them complex...but there are electronic versions...Im not sure if AEM allows it. But it'll detune the motor whilst you have the clutch dumped and throttle pegged until there is enough speed in the car to bring on full power. Like I said, I dont know how AEM's stuff works, but if boosting off of the line is the issue, then look for something like that. I can't remember the name exactly, nor the company, but I'll find it.

 

To give you all an idea of the power of this turbo . . . . previously I was able to hit about 2.2 bars and the boost was falling down to 1.6 - 1.7 bars at red line.

I was using 780 cc injectors wth 5 psi more fuel pressure than stock and running 92 - 94% injector duty cycle max

With the install of the new turbo - I have already hit 100% injector duty cycle at a very low 26 psi max !!!

Time for some bigger injectos - 1,000's on order

I just hope that the 255lph Walbro fuel pump will be up to the task of supplying enough fuel for at least 30 psi of boost and an estimated 560 - 580 whp

After driving this beast about all afternoon at 26 psi - I understand now why we all need BIG turbos. There is something very magcal about having a 4banger with a giant hair dryer kicking you in the *** so hard you are sure that something is about to blow up or go drastically wrong at any moment. somehow that 4G63 keeps taking the power every time i turn up the wick and keep coming back for more. I have 12,000 miles on this built motor now - its amazing how muc abuse I have put it throgh. Right now it hits just as hard as the old turbo used to pull last year when I was running it with a 75 shot of nosand full boost.

The big trick I guess is not getting caught OFF boost lagging it down low in the revs. A the track its really perfect. I can not wait to see what kind of mph this set up is going to pull down.

As for the lauch contol - the AEM has avery nice two step set up - so far I did o use it as the ar was already building too much boost off the line - depending on how it goes with the new turbo I may play with the launch control and see how it effect the launch. What really need is some bigger tires and a LSD f dif

 

You might want to look into the Supra pump. My recollection is it flows more than the Walbro. I think you can get it at any Toyota dealer.

It was an easy replacement with the VR 4, which could also run the Walbro, so maybe it will work w/ the Evo. Any good VR 4 tuner can give you the specs.

Either that, or turn up the juice on the Walbro.

 

Do I get a discount now that you have used my name??

 

Sadly due to the plastic fuel pump cage in the Evo it does not take that easily to bigger pumps wuch as the supra or the even bigger cosmos pump (like the one I had in my WRX back in the day)

A nice cosmos pump would be a very good solution to the fuel supply problem - but i think it would require a lof of difficult work to install it

As more and more evos start to reach into the high whp numbers - it may become ecomnomically feasable to produce a kit for the instalation of either two walbros or one bigger in tank pump

I was speaking to Martin at AMS and he has something like that in the works

 

Well if you look at his new web site, I'd have to say no!

 

What about increasing the voltage? Wouldn't that increase your flow? It might take an electrician to figure it out, but have you considered it?

 

BTW, have you seen the RC site. They can test the Walbro if you want them too.

Better them than your motor!

 

Al,

A couple of thoughts:

Try playing with the vss(vehicle speed boost control on the aem). You can launch and dial in just the right boost to stay at the limit of traction. It has worked for the monster dsm drag cars for a while and is more precise than the traction control by itself. It also makes the car much easier to control in turns on the track.

Going with bigger tires is probably a must but over 265's you will have to keep an eye on your hubs- especially if you want to do any road racing. Lose a hub and you lose the wheel.

Upgrade that fuel system! Seriously, I am feeling sorry for that poor walbro. The rre car killed a motor over a walbro in the over 500whp range.



Good luck

 

i should be home in ohio at that time sounds great. when can u take me for a ride?

 

Ahh yes, 1000cc's very nice. Thats what I am running right now, it nice knowing that I will not ever have to upgrade my injectors again.
