Daniel's 821whp SLR2.2 4G63 3794 TS
If you have been following us on facebook or in this thread- https://www.evolutionm.net/forums/al...ng-3794-a.html , then you know Daniel has been waiting on a monster to be born.
The main ingredient is a concept we visited in Nov of 2009, had an issue and left for the LR2.4s that we have been doing. The only complaint has been the increased bearing wear and reliability above 9,000rpm.
Enter the SLR2.2
Short Long Rod means 153mm in this case, when coupled to a 94mm crank, gives us a R/s of 1.627 which is the same step above a LR2.4 as the LR2.4 is above the SR2.4. The 85.5 x 94 ends up being 2159cc where the 86.75 (4G64) is 2222cc.
Mods-
ER SLR 2.2 10:1 compression
ER Jeff Bush Ported Evo VIII cylinder head w/ 1mm over valves
Wiseco 1400HD 10:1 pistons
R&R 153mm I beam connecting rods
K1 94mm crankshaft
Forced Performance HTA394 with twin scroll 1.15 V-Band
FIC2150s
GSC S3 camshaft set
GSC +1mm Valves
Kiggly Beehive valvesprings
Magnus V5 intake manifold
ETS Forward facing turbo kit with twin 38mm MVS wastegates
ETS 4" race intercooler w/ 2.5" piping
Buschur Racing double pumper
3" Ebay exhaust re-engineered with a Vibrant Muffler and 3" dump
Boomba 75mm TB
AEM Series 1 EMS tuned by Lucas English
E90ish
Here is what it did, filter off, dump open-
Observations-
The 1.15 housing is almost too small as the boost is dropping out the top vs my 2.4 motor which was able to hold 2-3psi more at the same level. Daniel needs a revised fuel system as this was done on stock lines and fuel rail which we know will get us away from the 95% IDC we were at to make this power.
It seems the extra displacement and MIVEC made up for around 600rpm better response on the same turbo. I say seems because we saw a 42R pick up 70whp and 200 rpm of spool going from a 1.15 to a 1.28.
After he gets a chance to enjoy the car, get the fuel system finished up, we'll revisit this with a little more boost...and ECU controlled boost instead of the TruBoost.

Aaron what is his plans for the car as far as track/daily/Road course? I know Myles and I talked about this setup for my upcoming build and I am just worried about no long term results. Mainly I want to know if he is going to drive the car or if it is going to sit in the garage and see less than 1k miles a year as my car is going to see several thousand miles a year.

That's just awesome, you guys never fail to amaze me. Definitely need a larger ar for more top end, and the 3 ports definitely will get more boost. I think with just 15 lbs springs will give 50+ with a 3 ports. We're building a 4g64 87mm bore with a k1 88mm billet crank and using 156mm rods with 6766, I'm wonder how it will stack up to this. Originally, this is what I wanted to build but didn't know anyone makes 153mm rods.

We're gonna need a SECRET trans for this car before too long 
This is what was on the dyno when we were talking on the phone that was making all the racket.
