You and I both!

What is your build? Heartbeat? Twin screw?

Ohh. Ok. I was reading a blog about your car and it said you are currently running a Stage 4 cam with a 102mm. I was wondering what the comparison would be. I would think the Stg 3 would make more power and tq in the lower rpm range then the stg 4 where you should see higher peak Hp numbers.

I have an LSA. Stock cube lower end but forged similar to the direction you are heading. I am running less compression than you plan on running. I have thought about swiching the LSA for a heartbeat but I’m unsure if it will net me enough power to warrant the change. Cost vs benefit.

Does NW make a 103? What is the cost over the 102? What intake are you planning on using? Are you planning on running Meth?

Wiseco Did introduce some of the mods that will be installed into their article incorrectly so it did confuse some readers like yourself..

The Stage 3 PD has worked great at 9lbs however I will be shooting for 18+psi at which the stage 4 will take over more on the top end where needed..

I agree with the LSA to Heartbeat change.. what are you making currently?

I may run meth but if I do it will only be to use it for its cooling benefits. Nothing more.

[Ajax2112]

I mentioned meth because of the cooling benefits. You are planning on running some serious boost along with the high compression it would definitely work well with your build. As far as my numbers go check out the Dyno thread in the ZL1 section. I believe it’s on the last page. I posted a screen shot the other day. The numbers are on a Mustang Dyno as opposed to a Dynojet which seems to be more commonly used around here. I have a little more tweaking to do before the summer so I will be watching to see how the Heartbeat performs.

You have to think about what intake your going to run. I switched from a Rotofab to a New Era and picked up some really nice gains throughout the curve.

I went a bit overboard already with the cooling mods so meth will be introduced after we get an idea of how the car responds. I am going to be running a prospeed Heat exchanger with 1” plumbing along with a Stewart EMP pump and an AFCO radiator...

I am working on getting an AFCO 5” intake.

Your IAT’s are going to climb very quickly with the boost level your aiming for. Are you planning on adding fans to the heat exchanger?

I’m not familiar with the intake you mentioned. You need to consider something that is pulling fresher air as opposed to air from inside of the engine bay. That’s why I choose the New Era. I went with the New Era 4.5” based on the experience of my tuner.

I wish someone would do comparison on 4” vs 4.5” vs 5”. I know Jannetty had done something in the past I wish he would do it again so we can see if there is an appreciable difference between them. Not just peak numbers but how the intake affects the torque and Hp curves. As far as the 1.9 LSA goes I have been told that the 5” can pick up peak HP numbers but at a sacrifice to some areas along the curve especially affecting the torque curve.

No fans. Fans imped/block airflow through the HX when needed most. I picked the cooling mods very carefully.

Are you building a race only setup?

Essentially. The car is not my daily and will mostly sit as I have two other vehicles I drive. This build will attend mostly Halfmile events as well as car shows and the occasional weekend cars n coffee ETC.

I forgot to respond to this.. I Have been Hounding Mike at Roto-fab for a 5'' option for the 5th gen but haven't received any response yet.. Maybe he will chime in if he see's this Post...

Who’s doing the machining and assembly of you engine?

I heard that name a few years ago. You may want to ask him about the br40 and dt40. BR30 is the usual go to unless he like his tolerances on the loose side.

Did he spec the compression ratio and the boost 18+ your planning on running? I’m also surprised he didn’t talk you in WCCH heads.

The oil was spec’d per the bearing clearances. Everything was spec’d accordingly. Richard at WCCH is a great guy.. The BR7 spec to WCCH likings is a great choice but we preferred the AFR heads on this project.
