You have to remember this "crap" I am posting is not just junk I learned from reading crap off the internet... I have been running E85 in 500+whp 3800s for 3 years now.

airflow.....
You have to remember this "crap" I am posting is not just junk I learned from reading crap off the internet... I have been running E85 in 500+whp 3800s for 3 years now.
So you're contending that airflow is my limiting factor to 374whp and I will not make any more power by setting the car up for a better fuel?
Smaller pulley and more timing. I really should have been on the 2.6 with the open down pipe. Boost dropped from 14-15psi to 11-12 psi with the exhaust opened up. Non intercooled, the TVS should be run around 14psi and timing around 20* on ethanol. This is a lt of guesswork right now but that seemed to be where the car ran the best.

Alright, so I wanted to break this down and see what it would cost to replicate this project. So here is the list of parts and prices that I came up with:
Autolite Spark Plugs AL-104 US $12.00
XP Cam Package US $324.99
Valve Spring Retainers 04-01-01157 Modified steel US $44.99
Crow Cams Valve Springs CROW-4918-12 105 lb US $109.99
Siemens Deka 60# Injectors 09-50-001100 Standard EV1 US $249.99
Northstar Throttle Body Kit ZZ-NSTBK-5-MAF Used LQ4 MAF US $299.99
ZZP Subtotal US $1,196.95
Headers and Exhaust Work $200
Supercharger $1500
Adapter Plate $300
Tuning $100
Racetronix Fuel Pump $210
Grand Total : $3355
Well... Let's just figure it out ourselves. First off, I have an XP, not an XPZ. So I fixed that.
Cost for GenV to make similar power.
Autolite Spark Plugs AL-104 US $12.00
XP Cam Package US $324.99
Siemens Deka 60# Injectors 09-50-001100 Standard EV1 US $249.99
Northstar Throttle Body Kit ZZ-NSTBK-5-MAF Used LQ4 MAF US $299.99
ZZP Intercooler with modded fuel rails (the cheap ones) $1319.99
ZZP Stage 3 heads (comes with springs) $1599.99
ZZP Subtotal US $3807
GenV blower + MPS and pullies - $500
Headers and Exhaust Work $200
Tuning $100
Racetronix Fuel Pump $210
Grand Total: $4817... Nearly $1,500 more.
I didn't include any of the little stuff either, which we all knows adds up quickly. Like gaskets, fluids, bolts, etc, etc, etc. Right there you could probably add on another $500 easy. And a one time base tune for $100 that you can't really do any changes. Anyone looking to make the 375whp mark would probably want to get a tuner and do it themselves since E85 octane levels seem to vary so much.
Another great benefit of the TVS is that you don't need to go any deeper into the engine than the LIM, that's it! You also have the option of doing things like heads/IC ON TOP of doing the TVS for even more power.
IMO, an honest comparison. Right Zef?
do you any of you guys believe in using a local machine shops to do head porting for significantly less then zzpoops?
C&S is getting a set of my heads soon.
edit because i dont want to make my own post: yup, them. in butler. i would definitely take something to them with zero worries.

I would get knock on the street from time to time. It didn't knock on the dyno though... I really regret not bringing the 2.6. Might have been good for another 15-20whp with tuning.
Lulz your cost chart of the heads cam IC gen5 setup look just as retarded compared to a Turbo setup that will stomp BOTH!
Umm pretty much just the IC + Head cost in your breakdown makes going turbo a no brainer!
"disclaimer hope I dont get an infraction or something lol"
Option C turbo kit costs less than 3XXX.00
Ya know... I've been going over the dyno scans and there was some funky stuff happening. My ECT sensor kept popping in and out during the runs, sending commanded AFR all over the place. That and the dyno operator didn't take the car past 5700rpm on the last 2 runs. I told him 6500... I made 369whp at 5700rpm on the very last run. The 374 runs both had numbers 15whp under that at 5750 on the graph.
I may have to go back...
Hmm, not really now that I have a second to look into it. Since E85 isn't available to everyone, and to make it a fair comparison, I looked at your base number of 350whp. Looking at the HP chart on CGP, there are several of people that made 350whp, or close to it on stock heads. So the ZZP S3 heads are not a necessity to make comparable HP to the TVS.
So this is the price list that I came up with:
Autolite Spark Plugs AL-104 US $12.00
Crow Cams Valve Springs CROW-4918-12 105 lb US $109.99
Siemens Deka 60# Injectors 09-50-001100 Standard EV1 US $249.99
Northstar Throttle Body Kit ZZ-NSTBK-5-MAF Used LQ4 MAF US $299.99
X-P HOT Cam COMP-3312/3324-116+2-XP Modified Retainers US $344.99
Intercooler 08-01-0061708-50-0063609-01-00534 Modified Fuel Rails Bosch pump US $1,319.99
ZZP Subtotal US $2,336.95
GenV blower + MPS and pullies - $500
Headers and Exhaust Work $200
Tuning $100
Racetronix Fuel Pump $210
Grand Total: $3346
Compared to the Updated TVS build:
So right about even to get the same amount of power. That is a more honest comparison in my opinion.Autolite Spark Plugs AL-104 US $12.00
X-P HOT Cam COMP-3312/3324-116+2-XP Modified Retainers US $344.99
Crow Cams Valve Springs CROW-4918-12 105 lb US $109.99

Supercharger $1500

Racetronix Fuel Pump $210
Grand Total : $3326
Those guys on the high hp list are all on race gas or ethanol. My being on e60 only leveled the playing field.
well zzp claims hooper made 30 WHP more on his VS cam engine with S3 heads.... little do they mention that was on race gas.
So 34x WHP on a VS? not really.
In this sort of situation, you really want proof they were on pump, not vice versa.
