Default P.R.E. 82X89 LSV dyno

I know some of you guys have already seen this but i figured it may be of use for some members on here. I built this lsvtec on a budget with simple parts and this is on just pump gas because it doesn't have the crazy amount of compression that everyone on here is used to seeing. The car has gone 12.33 at 110+ mph, weighs over 2300 lbs, and is our daily driver.

Still looking to see if more power can be made (if my budget will allow it) with a different header (Jack Myers, SMS, etc), some Rocket Cams, E-85, etc so we'll see

Setup is really simple:
82mm RS ITR Pistons
LS crank
stock rods with ARPs
Ported GSR Head
Skunk2 Pro2s
Rocket SL valvesprings
modded Px (Dynochart of stock Px on page 4)
Tegiwa Header (Toda Copy)
70mm TB

-Tou

Shortblock Assembled


Rocket Motorsports "Snap-Fit" springs


US ITR Pistons not PR3s, P30s, PCTs haha


Modded Performer X

Derek, yeah I did the tuning initially as you saw in the video. This was tuned by MA Performance after though because I wanted dynojet numbers.

Compression came out about 11.53:1 after cc'ing the head, piston to deck, and the rest of the measurements. Like I said before, it's not the usual high compression build that everyone usually prefers to see. Compression is also not the end all be all.

are those SAE, STD, or Uncorrected numbers? strong setup. any idea how much the head flows?

what was done to the performerX? any ideas on the flow of the plenum? any changes to the runners?

What transmission is being used in this setup? Very simple and effective! Great job!

awesome power with this CR, people overated CR almost all the time without taking time for the detail that really makes power.

the only thing I don't love on your setup is the stock rod @ 9400 rpm

Numbers shown are of STD correction. We didn't flow this head but similar to others we’ve done before which flows around 280 cfm. I had MAP mod the Px by shortening the runners and then blending the transition from the plenum into the runners. Similar to the King one but runner length between mine and theirs may be different.

Thanks! Ive seen your Pro1 vs Pro2 graphs too and agree that compression is not everything.

The stock rods with ARP bolts have been going for 3 years strong of daily driving and numerous trips to 10k rpms haha (knocks on wood)

Always love your builds ,the numbers are amazing , it just shows you with the right person building a motor you can accomplish great things . I finally got my car running hope to see the dyno soon , going to try to compare a custom header to a off the shelf header and maybe cams etc
Any pics of it on the track

For sure with a B swap, Si, 200 lb driver etc. Need to get into a lighter shell like yours

Love this build I need a similar intake manifold and some e85 since I have probably 12.5-1 compression on a 1.8 also just gsr crank and only 81.5mm pistons

Nice numbers, can't believe you're trying to make even more power than that! I can't wait to see the end results.

Great build. I have a similar build I'm helping a friend on. I believe I pm'd you a while back about it. Hoping to see at least 210. A custom header should definitely get you some nice power.

I can you tell you on my car which is a 1.8 with ctr and a gsr crank it was +3.5intake +1.5 exhaust or maybe the other way around can't remember haven't looked at them in awhile haha but a good 2* of seperation never got to moving them around because I need to go E85 since all i had was 22* of ignition timing before we started to get pinging,
