Plans are ARH 2 inch long tubes, rotofab, and magnuson 2300. Plans are to proceed next year with cam and heads, but wanting to keep it simple till new smell wears off. What kind of power is safe through A10 without fuel mods?

I wound up at 708whp on mustang from 520 with M6 car on mustang dyno. I have ported stock heads, 103mm tb, and cam but 1-7/8" ARH headers with rotofab and magnuson 2300. Low side fuel started to give way once we hit 700 whp but is still safe there. Looked like we could have reached 740 but that would have really been pushing low side to below 50psi likely.

Thats 750-775 on a dynojet. How are IATs with maggy?

I added the voltage booster and see 70psi all the way to redline. Everything looks good to about 740whp and will be upping the boost by a few more pounds next week.

Both you guys have a cam for high side fueling. Without cam where does it run out?

Based on what I've seen here, it seems to be about ~650ish rwhp, but I'm curious to see if anybody made more without taking apart the engine. Only exception seems to be a blower swap to a procharger type unit.

With our Boost Freeze Chiller, you can pack more timing into the tune. We saw 4* more timing, ZERO knock, 60ish whp more if I recall, 35* water temps, 10% less boost due to the freezing cold air going into the engine!

We made 685whp with only 12 psi on Intimidator's setup in testing and his only mods were:

• WEAPON-X Stage 1 Intake
• WEAPON-X 15% upper pulley
• NX Lid
• WEAPON-X Boost Freeze Chiller
• WEAPON-X Ported Supercharger
• 103mm Nick Williams TB
• 2" Kooks Headers
• Flow Master Mufflers (no power just sound)

We can run up to a 23% pulley combo before we see rail pressure drop on 93 octane, so I REALLLLLLLLLY want to get him back in for a lower pulley and see where it ends up. I put the over/under at 720!

The best part about our chiller is the fact that it makes your power repeatable and you can not only make MORE power, but you can also drop your temps right back down after a run within minutes vs. an hour!!!

Usually in the 750whp range give or take, but the low side drastically helps the high side. The pump will cavitate if it doesn't have a constant feed supply and that is when you start to see knock in the logs regardless if AFR looks "OK"

I put this together for you guys earlier this year in case it helps:

So if a low side enhancement is added, the high side will support 750 rwhp? Thats a good start on a build for sure. I appreciate you posting!

How far can you push the LT4 with Mag 2300 and low side fuel? No cam or any other fuel mods.

What about on 91 octane?

with a cam yes

you get a little more airflow with less boost but you still need the fuel, so you're still around 650-670whp

unfortunately less due to lack of timing
