I don’t want to say the shops name just Incase it’s not accurate so they don’t get burned. But I recently saw a lt4 car with Magnuson 2650, 112 Tb, and 5” cordes intake make 910whp with no E85, no meth, and no low side fuel system. In a way it makes sense. 15lbs of boost on a 1.7 supercharger, could be bade with the same amount of power on 10lbs of boost with a bigger super charger because it’s more efficient. My question is has anyone ran the 2650 with the 112 Tb? What kinda power are you making? Has anyone ported the 2650? Iv seen that jokers offers full tilt port on it, I would imagine that would help too.

On E85 with no low side seems very high to me. I had a 2650 with 103 and we made 870 on VP MS 109 race fuel , Lt4 Highside and injectors, Zl1 low side fuel pump and a boost a pump so 900 plus on E is questionable and I'd guess it would be out of fuel before you got close to 900 plus.. Unless you have a lot of mods I don't think the 112 will benefit most Lt1/4 motors. I've seen a couple that have been ported but they really didn't make enough power to be worth the cost. Magnuson did a really good job on the ports and can make over 1200 rwhp as many have already.

not putting your car down, but I made 840 to the wheels with a ported blower, Meth, e85 with low side. Cam and ported heads. The guy tuning the car is well known. I know some tuners are better at pulling out the fueling on these cars more then others. The slower u spin a blower the more efficient it is. So what if big of but what if it’s possible. It was a newer zl1 Camaro. Unless they have a fuel system upgrade from the factory I don’t know about

We could have made much more but when the low side is dropping into the 40s then not going to push it plus we were only on 13 lbs of boost so wasn't close to pushing the bounds plus we weren't running any meth either. Mine was an Lt1 Camaro, my C7 is just bolt ons and I never worry about what the dyno says it ran 9.33@149 at 3900 lbs so not worried about numbers. My heads were bone stock except for the springs and no porting on the blower as its not needed.

I have a 2650 with a 103 tb, 5" intake. At 16 psi I make 935whp but I have a lowside and am spraying meth. 910 with no E85, low side, or meth sounds questionable. Dangerous possibly? My tuner said he wouldn't go over 800 without meth when not using e85.
I am just at the limits of fueling and can go up 1 level in pulleys. I wonder what voodoo magic they're working on that car.

JaimeVette27

I agree with y’all, I was just wondering if anyone else had a 112 Tb with snout. Just like if you were maxed out and let’s say 15lbs of boost kn the stock blower and went with a procharger or bigger blower, same psi but more efficient makes more power. Blower is spinning slower but giving u more air so more power. I was just thinking shoot could 103 to 112 make that big of a difference. Can I ask why you went with the 103 instead of the 112?

I had the second or third 2650 built back in 2019 when I was working/drag racing for Magnuson and at that time the 112 was in development and not available yet but since I already had a 103 on my 2300 Maggie I just moved everything over to the 2650 since we were busting *** to make it to the 2019 Camaro Fest in early July. I know some of the Gen6 Camaro guys are running them but my buddy Jason Leiva which is the 2nd fastest with a 2650 at 8.48@163 just went to a 120mm TB but has been running into belt slippage so he's waiting on a new Ten Rib setup from Mike at Toohighpsi. His Camaro make about 1250 rwhp so it will make more as soon as the issue is resolved and should be able to run 8.20s or so. The 8 rib just won't hold the power

JasonVette

I wasn't aiming for that much power, especially not at the time.

If anything else worth comparing to, Vengeance car's make about 870 on 93 with no meth (but with a lowside). I don't see a 112 making an extra 40 to the wheels with no low side.

On the topic of anyone having done it. I don't see 112s and ported 2650s unless people are north of 1k. At that point they have all the fueling in the world with injectors, hpfp, meth, etc. to make it worth it. Can't help with that, but I'm sure a handful have done it.

Right now I have 840 to the wheels on the stock blower. I’m running a 9.5 at 151 mph. My 60 is bad at a 1.59. Not bad but not what it could be. I’m on a 18” wheel. Do y’all think doing a 2650 bring around 930 to the wheels will get me a 8 second pass if I do the brake conversion in the rear? Will that be enough power?

JaimeVette27

do you drag race your car? Have you broken into the 8’s?

I am running a 112mm TB with Magnuson 2650. However I don't have an A-B comparison as I did other things at the same time

I used to run a Nick Williams 112mm TB which I got in early 2020. At 20+ psi, the throttle blade started to get sucked shut. Last October I switched to Katech 112mm TB & never had such problem

JaimeVette27

what other mods do you have? How much power are you putting down

Corvette4ever

My car is a GS not a Z06. Forged bottom end & ported heads with stg 1 cam.

No idea on power, but my best ET is 9.21@149.3 in 2000+ DA running VP ms109 (no meth). I would guess the car should put 900+rwhp on a dynojet

99vetteran

That has to be real close to correct on the rwhp considering the GS is probably 350 to 400 lbs lighter then my Camaro was.

JasonVette

I do not. Another 2650 car built by my shop managed a 9.1 today, but it has more power than I do. I'm not sure what it takes to get to 8s on this platform. The stock blower seems better if you're chasing times unless you really spin the 2650.

JaimeVette27

Is your shop located in tx by any chance? I got a great tuner here but haven’t gotten my data log I did revised in over two weeks.

99vetteran

On the Gen6 Camaro side called the fast 20 there is an Lt4 blower car thats run 8.80's in the mid 150s but they are spinning the hell out it. Both the Magnusons in that fast 20 are running 8.40s and in the low 160s mph. They both are on about 23-24 lbs of boost, both cars are just under 4000 lbs with roll cages, Jason's Zl1 with A10 and Mike Swanson SS with A8 has been 8.40 on the stock 2650 blower, no porting on the blowers. Jason's Zl1 has been over 165 mph in the traps so its makin bacon on the big end.

JaimeVette27

that’s very impressive. I’m running a 18 percent lower and a 2.3 upper. I wouldn’t know how u can spin it any faster without heat soak. I trailer to the track and run two runs only. I always get kicked out anyways. I will not put a roll cage or a parachute. I’d like to hit a 8 with my stock blower. Would be nice to do it on my 18” wheel maybe at Houston track it will be possible. With a 100 shot or somthing

JasonVette

That's a lot of PSI. Easily 1k+ whp on those 2650s I'd imagine.

My shop is in Houston. My tuner is Matt Sorian of MSTuning.

JaimeVette27

is he good to work with? I would like someone that goes to the track and invites even if u gotta pay to tune it at the track. Or at least responds to revise a data log in a normal time frame.
