I did a blower swap without doing a cam first. If I had to do it over I would do the cam first. You need fuel. Save your money for a blower down the road.

I would go with the Build B (2650)...that's VERY similar to my imminent build. Drive it like stock or blow someone's doors off, your choice! haha!

If you had to choose one and goals are 9.7-9.9's and be able to drive it anywhere without issues. Basically, Cam or larger SC? In addition to either i will add a Drag Pack 17" rear and 18" fronts.

I could be wrong, but i am thinking to do both at the same time would be appx an extra $5k. I keep flip flopping on my decision now that time has gotten so close. Need input!!

Mod list A
Cam
Oil pump
Kong w/103TB
Big Gulp
ARH 2", resonators, ARH exhaust into stock muffler
Pump booster and e85 kit
Pulleys 1 or both
Tune

Mod list B
2650 supercharger
Big Gulp
103TB
Pulleys 1 or both
ARH 2", resonators, ARH exhaust into stock muffler
Pump booster and e85 kit
Tune

Wondering why you would need the oil pump and have you rrsearched which port work is better? The fulltilt or kong port.

Also, what booster are you talking about? From what im tracking all you need to run a Ethanol blend is the low side and flex fuel but than your just dealing with fuel mixtures. Why not run meth to supplement the fuel.

Ive yet to rrad about anyone blowing a stock supercharger daily driving or even doing long pulls. I would think that your tuner would do some road tuning to make sure they werent over spinning the shitnout of a stock supercharger to keep it happy. There are quite a few low to mid 700 whp cars on stock cam and heads.

I think that at 13K miles, if you were gonna have OP problems then they would have surfaced by now. I'm at 18K miles and no OP issues at all. So I think you're safe. EDF Hobbies knows his stuff. So i would consider what he has to say. But I am not a fan of porting the stock blower. And I fell in love with what the 2650s can do while under 800 RWHP. However other options include the E-Force (depending on your end goals). EDF can elaborate more on that.

My build is gonna start off with LTs, tune, and 2650 swap hopefully later this year. If I so desire then next year will see a cam/heads upgrade along with whatever fueling upgrades are necessary. After that if I desire to go further then I'll see what the E-Force has to offer. Or a PC blower. We'll see when I get there!!

It is possible



ported stock blower/meth/bolt-ons... stock heads and cam.

I would call Ted Jannetty and explain to him what your goals are, I called him and he is very intent on listening and giving good advice, plus he is a tuner so he may see something you don't in your build list. Just my two cents worth , he is very cool.

Have you run your car? Your mods are similar minus the cam, but added meth, so pretty close in power numbers.

4 ways to build a fuel system 3 logical choices for fuel unless you want to be meth dependent and or race gas dependent!

From cheapest to most expensive...

Cam or your choice with the 38% fuel lobe/7.85mm fuel lobe
LT4 Fuel Parts
Meth/Race Gas
DSX/SMG low side Aux
DSX Flex kit or SMG
Obvious choice for most since its the cheapest upfront cost.

Cam with 8.2mm lobe
FIC injectors/lingenfelter/XDI size of your choice 30, 45, 60
lingenfelter Big Bore pump (spaced correctly)
Return style low side with 100 psi and load of 80 psi never dropping off
Free flowing ck valve in the new feed line
DSX Flex kit or SMG

Port Injection by Crawford Racing or others if blower allows it and some type of ecu to run it w wide band.
DSX Flex kit or SMG

XDI katech System
Low side with 100 psi/80psi under load
DSX Flex kit or SMG

I really don't like to put a HP number on it because the power adder can move that number around depending on how much air its moving at the same psi as others and things like how much HP is spent to make that psi sum it in 1 word efficiency of your power adder.

I'd weigh in the ported blower vs the 2650 the only way to do this is try to max out the 1.7L to what the 2650 can do using about 50% of what its capable of doing with its better efficiency. Let's use a dollar amount and IAT's to compare with for a 800 rwhp goal

Not going to list headers, TBs, Aux pumps, or CAI you need that regardless of your direction..

$999-$1300 plus ship maybe a box charge Ported blower (full tilt 45hp mambo jambo)
$395-$1300 Heat exchanger(ADM, AFCO, ProSpeed, Wp X, PLM
$500-$1000 Larger Reservoir for capacity and better intercooler pump
$800 to $1200 Meth kit
$250 Griptec pulley
$600 ATI damper and Blower ring
$XXXX CAM


I can't see spending that ^ to do what the 2650 and a cam can do on 93 only! (plus you can subtract 1500 to 2000 selling your oem blower)

next you need to Factor the 2650s..

$5995 plus 200 for a snout for the Maggi
$4800 plus 1275 for porting However usually a 500 off from Edelbrock or 500 off with a 10% code from Summit Racing..

You don't have to port the eforce of course unless you going all out but, Mike(magunson) mentions there's is ported from the factory so if we are going to compare everything lets do it you can clearly see Stock to Stock how much area is opened up compared to the Eforce, But, once the Eforce is ported its opening is larger than the maggi's.

See pic left Side Edelbrock ported and stock, right side Maggi.. Doing the porting picks up 100hp and lowers the IATs to the same or better than the maggi's. It's not the bricks so much as the velocity and flow.. faster air speed over the IAT sensor will lower the temps.. This is the same ares that's massaged on the oem blowers by Kong and jokerz along with the snouts. They really clean it up and make them flow more and the oem blowers are now more efficient if you don't over spin them lol..

There is a 2017 zl1 in the drag racing section making over 750 whp on a cam, low side+flex fuel, on e55.

Everything i read on the whipple 2.9 was without a good cam and at least injectors you are going to run out of fuel pretty quick and not run enough boost to even be worth it. Everything i read was that heat was the killer for the 1.7 but i dont see why bigger heat exchangers and more fluid couldnt help keep the 1.7 blower running more efficiently.

B in progress here. 2650 has been on for a bit. Big Gulp, 95mm tb and JMS are on. Headers are in the box and ready to install. Not doing E85 and sticking with the standard upper - 90mm and stock lower pulleys. Headers on soon and then a remote tune by Ted J.

What power and boost are you making with what you have now? Where were your AITs at on the dyno if you dont mind sharing?

[SienarSystems]

Unfortunately, I won’t have new dyno numbers. 641 hp with the 2650 and Magnuson’s tune. 90mm pulley and stock lower. Don’t have boost #s or IATs.

Not yet, just got mine back.
Waiting for the track to open up here in Va.

ok, thanks
