Looking for some sound advice on my next step "up"?

Current set up:

• C6 Z51 - Manual with original trans & clutch
• Corsa Exhaust
• American racing headers
• cold Air intake w/ K&N
• 160 degree therm
• Cam / Heads / Forged Piston & Rods

Wants:

• daily driver
• Fully functioning A/C (a must here in Florida....)
• "street" car (not taken to the track....ok, maybe once)
• 700+ RWHP would be nice but more importantly looking for 625+ torque?!?

I've driven a C6 with stock internals / ECS 1500 blower / Methanol with (625 RWHP & 565 Torque). This car was definitely fast but after driving my current set up it seemed like the "real" power & pull isn't there until you hit 4000 rpms or higher (the small little bonus with this was my buddy seems to always stay planted on the road compared to other cars out there with similar power and ..............he spends way less on rubber).

Would a positive displacement blower be better for the street? My gut is telling me ....yes!?!

The vibe I've been getting is that if I do go Maggie I would need better tires and maybe even a new clutch and that the A & A would be more "usable" power here in FL.? Is there"noticeable" difference between these two blowers.............will the Magnuson run considerably hotter here in Florida?

I feel like one of those "pan handlers" on the side of the street ......."Anything helps / God bless" kinda thing!! lol

Drive both and see what YOU like. The HB blowers run cooler, not hotter.

From what you said I would go with the Magnuson Heartbeat. The torque would be there as soon as you took off and the torque line will stay level or hold there but that's from the minute you take off. Which like you said with the A&A or ESC (Centri style blowers) from what I've been reading you have to turn up to 3500 rpms or higher to really get into boost which means your hauling. I've had a TVS2300 in a LS3 2010 Camaro and it was very fun in a six speed. But I was kind of like you didn't want to have to spin the supercharger high to have a lot of fun or make a whole lot of power. I just don't know how much rwhp you will be able to make if you go with the TVS2300 Heartbeat as I hear the Positive displacements are somewhat limited but I could be wrong I'm no supercharger guru or anything

ECS kits have a removable restrictor to tame the boost down. remove the restrictor and readjust your tune. you will definitely find out really quick how good your clutch/tires are.

HB Blower????

jaybee924

I think he's talking about the Maggie Heartbeat blower

flairbnb4u

Great idea.....anyone out there near Tampa or Sarasota with an available LS3 manual with a Magnuson Heartbeat I could take a quick spin in?

flairbnb4u

Yeah....as soon as I hit send it dawned on me .

flairbnb4u

if I'm hearing you correctly your saying with equally good tunes on the the same car the ECS & Maggie blower would net the following gains:

ECS..........150-200 HP (100-150 Torque)
Maggie..... 100-150 HP (80-130 Torque)

* with restrictor off the ECS would increase 20-25% from above?

If this is fairly accurate would both cars run about the same 1/4 mile times??

If you are pullied aggressively, you will have all the power you can handle out of centri blower. The problem with most people is they only want 6-8 psi. Well its not going to make that till late in the rpms because of the way they pullied. So either pulley hard and use a restrictor plate or pulley hard and let it have all the boost.

If it's a street car that barely sees the dragstrip just do the heartbeat. The centris really shine 800+ rwhp.

I have a 2010 GS with a Maggie, LG pros, and B&B fusion. Car made 548/502 at the wheels on the last tune. You will definitely get more with your cam and heads. There's lot's left on the table with my setup - pulley change out will increase boost, but my injectors are maxed out.

What I love about the Maggie is the instant power. All of that torque is basically on tap by 1800 rpm. Real tire shredder.

Sounds like you want torque. That's what a Maggie does best.

Edit: forgot to mention cool running. I'm in New Orleans (hottest place on earth). Magnuson has a great package - complete with cooling system that works. Never had an issue with heat even on interstate parking lots.

On the power side the HB is easily 650+ the way you're equipped. Maybe more with the ported heads. If you employ an O/D crank pulley, 700 is probably doable.

My last one did 664/612 with mild blower cam and bolt ons. That was with an 81mm pulley (smallest pulley that will fit over the blower snout). 10psi with meth. Wouldn't waste my time with meth again. The failsafes aren't there and it was only good for 20 hp over the non meth setup.

I had a Dewitts radiator on it and ECT's were cool to say the least. I actually thought it ran too cool with the 160 degree stat. Rarely over 175 when the Vette was moving. Would get to 200 if the Vette was parked with the A/C blowing cold. That's in 95* Texas heat and humidity. My previous Vette had a jackshaft Maggie (stock radiator) and you couldn't leave it parked in the summer with the A/C on for very long without the A/C shutting down. Still didn't over heat though. As soon as you got moving, temps went down quick.

flairbnb4u

Awesome!! The Dewitts radiator suggestion was a BIG help! I'm not sure we're quite as hot as you lads over in the Houston area (OMG it's frickin hot there) but I'm sure we're only a few clicks less! lol

Thanks again!

On my Maggie HB setup, I did as many recommended on this forum, when I swapped out my radiator for the DeWitt's on a C6 Grand Sport M6. I removed the external oil cooler by swapping it with the DeWitts in tank oil cooler to provide more airflow for the HX intercooler exchanger...
good luck and please keep us posted...

flairbnb4u

Perfect...........Thank you so much! Everyone on here is so helpful....wish I would've jumped on this forum a long time ago!

old motorhead

And you have the hoses already in place to just bolt the Dewitts radiator in. Chiselchst and I had to buy Z51 hoses to make it all bolt up. I'm assuming your stock radiator has the integral engine oil cooler now.

This. I went through the same thing. I bought a A&A TI v3 and couldn't be happier. I made 760 uncorrected(817 corrected) on my ls6. I make 2 pounds of boost at 2.4kish and 13 at 6.8k. The car hits hard and fast(stock long block ls6 car). I have a 3.6 pulley. I wouldn't want anymore down low as hooking would be a major problem. A pullied down centri is perfect in a light vette IMO.

I have a similar setup....Ls2, v2 ti-trim w/3.4" pulley making 13.8 lbs boost.....car is street tuned so don't know power #'s...but quick for sure

I would do the A&A Ti trim having worked with many of both.
