An awesome request, but on the insane side.

Can you confirm if this is in a standard chassis or if it needed to be an SV to have sufficient room?

What brand of dyno do you use? Do you ever do a run before install of the Kraft Werks kit to see what the gain is on the same dyno? I have seen dyno with a pretty wide swing in readings from one another. If you are getting 409rwhp from ten pounds boost that is more than double stock power level of a na AP1 and

AP2. All the NA s2000 I have dynoed run 186 to 199 rwhp. I have only done this on three cars on the same dyno so maybe his is reading a little low. In the end the numbers don't really matter it is how the car performance changes that is the goal.

 

Keep us updated on how the turbo works out on the 7.

 

I have a land and sea Dyno. On a Stock ap1 to the wheels makes on my Dyno is around 195hp ap2 210hp.

 

AP1 witha high boost Kraft werks will make 350hp to the wheels with a Greddy emanage

 

Keep in mind AP1 that made 409 had a AP2 engine in it with AEM EMS.

We also live in Florida, That means sea level. I guess that is one of many reasons I live in Florida. More HP and you can drive year round.

 

Bottom line is a Dyno is a tool and nothing more. long as I make more power than my base pull.

That makes sense. I didn't take into account elevation.

 

On 7evins car we are using HKS fuel management. We can run two maps one for pump gas one for race fuel. We also use a boost controller to set the appropriate boost level for the fuel on board. Street gas we run 9 psi race fuel is going to be 21+psi on new engine. Only difference in our set up and Kraftwerks is we use the next size up on the supercharger. It has a little different boost curve, we might not be as efficient at lower boost levels. We will find out on a few weeks when we visit Kenny Tran for a new tune.

I only see one problem in your build. The 6 rib belt will only support so much. There is guy here in Tampa and calls himself elroy on S2KI. I know he is in the process of running a bigger supercharger.

I know for sure mustangs run 8 to 10 rib belts on anything over 15psi or 2.1L positive displacement superchargers.

Have you had your rear diff built yet? If not, call Puddy Daddy he has built rears for Honda’s race team. In fact he built our diff in our 580hp S2000 and also our 1200hp 350Z.

Sean:

 

Ditto: you know you have "ample" power when you can break the rears loose when you drop the hammer in 4th, whilst putt-putting along at 70mph.

 

Mike

 

I suppose thats "ample" power, if you get the chance do that in a AWD STi that lays down 630 to the wheels.

I believe it's a narrow chassis. Looks like the first USA R400. It was later for sale at Aston Martin Orlando:

Thats way too funny, this is the same car and it belongs to the dealership as there fun toy.

Well we are almost finished gets tuned on Friday

We thought of the wider belt already. 7evin got ATI to build a custom damper and wider pulleys for all the drives to run an 8 rib belt. We are using a Subaru STI diff. it has been cryo treated and micro polished. Kenny Tran is rebuilding it for us. I hope that we can limit the belt slippage with it. We might need to come up with a tensioner that has a little more tension. We are a little afraid if it because you start overloading the bearing with to much tension. I guess we will see next week when we dyno if we are able to build that boost we want. We are going to spin the Rotrex to the max edge. It should do 25psi with pressure loss thru the IC and tubing it will be intresting to see what we actually get.

[SR Performance]

Good luck with that build, it sounds like you got all the bases covered.

[SR Performance]

Well its all finished and one of the fastest cars I ever driven

The car made 283hp at 8lbs on a very safe tune

here is a video and the dyno sheet

Sorry for the bad video

This is so awesome!! It's like riding a busa on 4 wheels.

[WestTexasS2K]

These cars take on a whole new definition of fast at that power level. It is hard to wipe the grin off isn't it.

[SR Performance]

We build some amazing fast cars here at S&R and I have become jaded to the business. So once in a blue moon a car will come along and suck the wind out of me like this one did. After we dropped it offed, the owner had a grin that would not come off.
