Bah! Where did you hear that?

AMS is definitely NOT using NOS (as you put it)... and i don't think UR is either.. but i can't confirm that..

11.85 on stock turbo w/o nitrous! ..and that's only so far!.... they would probably run even better now, since they've upped the hp quite a bit since that run!.. they were just a few hp away from 400whp last i heard..

AMS EVO8 =

 

just curious what mods have been done to the AMS evo8, and what octane they used to achieve the 11sec run.

 

"The Current mods are:

AMS Catback exhaust
AMS experimental o2 housing and downpipe
AMS Race Cams (Soon to be available)
AMS FMIC Upgrade
Greddy E-Manage
AMS 680cc Injectors
Walbro 255 HP Fuel Pump
Tial Race Blow Off Valve on STOCK Intercooler Piping
AMS Experimental MAF Tube with Cone Style Air Filter
RMR 6 Puck Clutch Disc With Stock Pressure Plate and Flywheel
SSR Competition Wheels with stock Tires on them

Non-Power Parts:
Defi D-Series Boost Gauge
Carbon Fiber Autometer Gauge Cup
Blitz FATT Turbo Timer
AMS Stickers (An Easy 50 horse at the wheels there )"

Buschur ran a 12.09 on PUMP GAS, STOCK FUEL SYSTEM and STREET CAMS and stock 02 housing...But AMS Never mentions what octane they were running?? I dunno, Both cars will be very close in performance once they have the "bolt'ons" maxed out. With 380Hp Buschur should best all the "bolt-on" times.

 

So what is the longevity of a motor spiking 24 psi? That is a LOT of boost. Just wondering if anyone has taken that into consideration?

 

Maybe I missed it, but did Buschur hit 380 WHP with their Stave 4 kit on pump fuel or 118 octane?

GMat...The only longevity problem is with the turbo at 24... The stock engine is stout...400whp+

 

24psi is baby boost dude. Maybe it's a lot for a Honda, but DSM's have been cranking down mid 30's boost (with appropriate sized turbos and fuel components of course) for years.

 

Man, that is nuts.

 

Alright, here are all the answers to the above questions.

The AEM we have in a prototype, it isn't even in a case, just a board with a plug. I imagine it will be quite some time before one is ready for sale to the public.

I would highly recommend getting the AFC II for now regardless of your future plans. It is just working kick *** on the car.

The injector, pump and tuning package is tuned for race gas and a peak boost of 24 psi. The tune is going to remain the same with 94 octane, you will just have to turn the boost down to 19 psi again. The new tune is more aggressive than our current version. We are running the car closer to 12.5:1 now than we were before.

The injectors we are having custom built, the same company that has been doing our injectors for a couple of years are doing these. The fuel pump flows 255 lph. There are quite a few different pumps out there. I think you will find that at $550 for pump, injectors, new fuel tank seal and the tuning instructions we are keeping the price low.

We just found out that the front differentials that are failing is because of a problem at Mitsu. They are shimmed too tight. I hear there will probably be a recall.

Doing the head studs one at a time would be fine in my mind. Start in the middle of the head and work your way out. We are no using any head, rod or main studs in our engine. Everything is stock except for the cams.

Yes, we are using a FWD dyno.

The 24 psi spike is nothing for a 4g63 to handle as long as the tuning and octane are where they should be.

Take care,

I forgot to answer one question.

How much does it take to get to the 380 whp that we are making right now. I am going to list them below.

BR full 3" exhaust, $750
BR intake and MAS pipe, $275
BR battery kit, $225
BR upper i/c pipe, $300
BR boost gauge and mount, $85
AFC II with BR tuning instructions, $340
BR injector, fuel pump kit, $550
BR FMIC, $750
HKS 264 cams, $580
BR boost control, $75

TOTAL=$3930 !!!!!!!!!!!!!!!!!!

This should be all it takes to make that much. This is up through our Stage 4 kit that we are offering. This does not include the Exedy clutch kit that we have in our car. This isn't needed to make that kind of power, so I am not putting it in the cost.

This kit above will put your EVO 8 into the 11's, I gaurantee that.

Thanks for reading,

$3930 installed, right?

Hmm, wife just got a $3750 check....I wonder if she would notice it was gone...

 

David, what about tuning for 91 octane? What kind of performance can we expect to see from your kit?

Would you run the car a bit more rich to prevent detonation?

Do you have a program for 91 octane?

Thanks,

Steve

 

Seriously? Where'd this info come from?

If it doesn't effect emissions, would Mitsubishi even think about recalling it?

 

The tune we are using for the car will work on 91-94 octane. We are not leaning on the car that hard, even on the race gas program. The only difference when changing the injectors/pump for our Stage 4 is you will turn the boost back down to 19 psi when you are done.

The performance with our kit up to stage 4 should yield you 11 second time slips at 115+ mph. We have already gone 12.09 at 115 on pump gas. The race gas+boost+injectors and pump will put the car well into the 11's. We will run the car soon and prove this.

Running a car richer will not always get rid of detonation. IF the car is too lean then YES it can get rid of it. If the fuel quality is too poor then adding more fuel will usually add to the knock count.

The t-case information we got was from a customer who has been through two transfer cases. He was told by his dealer.

Mitsubishi actually has done a t-case warranty/recall in the past on the early DSM's.
