You surely know how to tune a DSM CanadianTSI
Sorry to dig up an old post. I was searching and...400HP on a 7block is possible but will not last long. I've seen a stock Longblock 6bolt do 520AWHP on a FP3065. And still is running strong and lasting in everyday traffic.
This begs another question regarding "daily driver or all day long". Is this on pump gas? Here in Cal, 91 octaine is our daily driver gas. I know another guy here who has Evo9 and makes 380hp using E85 and alcohol injection. I know that we're talking about bottom-end only, but I can't imagine it can make such huge difference with head differences.There are several people pushing the stock 6 bolt mighty far. I personally have a stock 6 bolt bottom end with arp l19's and a perma torque head gasket and I also make 500awhp all day long. It has made as much as 597 on 100 shot.
Solid tuning and being smart about how you beat on it and take care of it, you should be alright.
Excellent! I'm guessing you don't use alcohol inj, I suppose if you use it, you could up the power level even higher. Am I right?It is a daily driver car, I just meant that any day you could throw it on the dyno and it'll make 500. I guess we are spoiled up here in MN that we have e85, but I get it from the pump so I just consider it normal pump gas. I still have a stock 1g springs/retainers with some cheap DKS cams.
This is correct. Harder, initially yes. But once you dial the GM MAF in, it all becomes the same as anything else. I recommend doing ZERO...
Tuning with the maf-t unit (for those with dsmlink) itself and you will be fine.
400hp is indeed possible on stock internals. Even a 7 bolt. You will need head studs probably at minimum. I would do rod bolts as well. You will need to dial the car in for absolute consistency in all conditions and avoid ANY knock WHATSOEVER. Which means you probably won't be pushing it out of that little T28. If it were an old FP KILLER 28... maybe... but even then probably not without race gas / or methanol injection.
You just cannot afford ANY hiccups at that power level on a stock engine. You are dealing with cast pistons, OE rings, press fit pins... and stock rod fasteners... Good? Absolutely... going to take a bunch of bullshit? No fucking way. I had a bad detonation event on a stock 7 bolt bottom end @ 28psi and it blew a piston into puzzle pieces and bent every fucking rod in the motor.
I wouldn't even ATTEMPT a run at 400 WHP on a stock 7 bolt without the following;
-ARP head studs
-ARP rod bolts
-Quality core FMIC
-EvoIII 16g / 50trim <bigger
