I just got back from my trip to North Dakota.

Tym made some great progress on the EVO while I was gone. He set the car up so we could dyno it again and went to it.

In the exact same form as it was in for the 12.09 at 115 mph run the car layed down 361 hp and 303 ft lbs of torque. This is an 18 hp gain over our Stage 2 package. (The changes for Stage 3 over Stage 2 were the 264 HKS cams and our FMIC kit). Doesn't seem like alot but the nice thing about the curve is this isn't just a 18 HP peak number. The car made more HP through the entire curve. This explains the nice drop in 1/4 mile times and increased MPH.

Tym then went to work on our Stage Four. He installed our 660 cc injectors and our high flow fuel pump. This required more tuning. One of the biggest reasons we made this change is the car is consistently hitting fuel cut with the cold weather that we are dealing with.

With the Stage Four package we are now able to up the boost and it sets the car up for the future turbo upgrade when we get it on the car.

With the new Stage Four kit the horsepower came up to 380 to the wheels. The UNBELIEVABLE part of this was the torque made the largest jump it has since we started on the car. The torque came in at 349.1 ft lbs.

This Stage Four package will allow for higher boost without fuel cut and let the guy that wants to really run the car hard at the track do it. We had a peak boost of 24 psi and it would fairly quickly settle to 20-21 psi. The boost drop is just from the compressor wheel in the stock turbo being on the small side.

We will be running the car again this week and expect to see a new stock turbo MPH/ET record come from it.

After we run the car this time if all goes well Tym is going to start tuning with the AEM standalone fuel management system. This is going to prepare us for our turbo kit.

We will be trying to crack the 400 hp mark with the AEM on the stock turbo.

THIS CAR ROCKS!!!

Wait.. AEM's EMS is finally out?? Agh..

 

David, I am going to be hopefully picking up everything for your stage 4 this Friday. How long do you think before you will have the AEM available, since I won't need the SAFC I was going to pick up if I get the AEM.

 

I saw from your site the 380 HP figure was accomplished on 118 octane and that was what the AFCII was tuned for. Are you going to include instructions for the AFCII with your stage 4 kit for 94 octane?

 

FYI AEM's site still says its not yet available..

 

Getyup...I have your setup minus your frontmount & IC Pipes(Next summer!)...

I'm about to buy injectors...which brand do you sell and the price...and the same for the fuel pump?

BTW: David is one or two tuners to have the prototype AEM system

 

Hi David,

Congratulations on your dyno/1/4 mile testing very impressive. I was hoping you could give some advice/info on a few concerns at these sorts of power levels.

I understand at least 2-3 people have had problems with the front differential. Does anyone have any ideas on how or why this could have happened, and what could be done to prevent it?

I understand that ARP head studs are highly recommended when you start making this kind of power. Are you using them? Do you think it is ok to install them one at a time without removing the head?

Thanks and good luck at the track,

Eric

 

Doesn't AMS say they are running 11.85 with stage 1 and cams (stock turbo)?

 

I think Ultimate Racing is too...

 

I think the AEM computer is going to be the way to go, they you can run anything and not worry about if the vendor is going to make a map. So far I am looking at the H&S turbo back then once David is done with the AEM and has a plug and play harness I will be going with that once it has some time to get the bugs worked out on some cars 1st. I think with the AEM you can run all your stock stuff and just plug it in.

 

What was the cost going to be on these number? By the Way, these dyno numbers are still front wheel only numbers, correct? I thought Buscher had a weird dyno coversion becasue they didn't use an al wheel drive dyno

 

both of those cars in the 11s are useing NOS i am not going to use NOS so i would rather listen to somebody thats doing low 12 without NOS... like David B.
and i would like to know about putting arp headstuds in so soon can this be true do we really need them??

 

aem has alot of bugs to work out before i think of buying it

 

That is why I choose to wait. It's worth it to me to wait 6months to a year so when I do mod the car that is not guess work. it's this this and this = 400 whp not well we can do this and see. :-)

 

The downside to all of this is it seems the limitations of the factory turbo are being reached... And I dont have money for a new turbo right now...damn
