Poll: What is considered a ZL1 "bolt on"? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Stephen12ZL1 · 12-01-2013, 10:15 AM

Just for fun let's see what the masses consider a "bolt on" with a ZL1 that has a factory supercharger. Merc clearly states that a "bolt on" is as follows: Bolt-Ons without Internal Engine Modification (e.g. modified airpath, headers, PCM-tune, aftermarket clutch, non-stock rear gears, skinny front tires)

OK...so now we are arguing over what does he mean by "modified air path"? My understanding is that a "path" is "a route or course along which something moves: the path of a hurricane.". So, air can be routed many different ways into the engine with various cold air induction systems and throttle bodies before the air enters the engine. Obviously, we must now define when something becomes "internal". Our ZL1 cars have a factory blower assembly with its associated metallic parts (snout, case, rotors). Airflow within the blower can be changed via porting the case & porting the snout. When does air enter the "engine"? Is the blower part of our "engine" because it is a factory installed part? Take the poll.

I voted it as a bolt on. a supercharger is a bolt on power adder already regardless if its from the factory or not. when I think internal mods I think of parts within the block that cannot be seen or be removed with a few simple bolts. technically heads are bolt ons, just a lot more bolts

I think it is not a bolt on.

In either case I am not losing sleep over it.

Your stock or your not.

Well normally most people think of bolt on's as external parts ! like my car everything is bolt on,but the cam...anytime you remove metal from a part its not a bolt on,its modified,changed to the point where it can no longer go back to what it was before.....a blower is not normally consider a bolt on,as of all the other parts that have to be installed on the car to go with it...that being said its not blk and white because they do make a complete kit that's all in one which could be considered a bolt on part....
The term bolt on's normally just means minor performance improving parts,but If you wanted to be silly about it,any part that has a bolt used with the installation of said part is just that,a bolt on part...heck a water pump is a bolt on part if it pumps more water than the part it replaces...

I love this answer but the sub-categories for 1/4 mile bragging rights has a bolt on section.

Clearly the CAI is not considered an internal mod and it affects airflow more than possibly any other mod. I feel the internal mods have to take place in the longblock to be internal. I think the reason they added the airflow thing is because if you bolt on a turbo or supercharger to a naturally aspirated engine you make so much gain no one else has a chance. Your blower and snout porting will give you slight gains but minimal compared to the boosting of NA engines. I say go for it. And besides, next is heads and a cam so you are probably going there anyway....lol.

BOLT/ON is more or less a ruling defined by LS1TECH of the guys who race, its nothing in the engine that touches oil so heads cam rockers valves, it only pertains to the engine not the trans or rear as far as a supercharger or turbo or nitrous then its forced induction. Basically from intake to oil pan, and the SC sits on top of the intake... So still a bolt on

Justins00ss · 12-01-2013, 12:42 PM

It is a bolt on. Weather you can except that or not is a different story. Deal with it! No different than porting a stock TB. Its not like changing heads or a cam.

ZL1-V · 12-01-2013, 12:52 PM

It always has been considered a "bolt on".

jdsgn · 12-01-2013, 01:20 PM

If you bought the snout pre ported and bolted it on does that change anything? Plenty of machine work goes into all the bolt on parts, just because you send one out to get ported doesn't change that it's a bolt on. All bolt ons effect airflow.

CamaroV6 · 12-01-2013, 02:05 PM

Supercharger is a bolt on just cuz it comes from the factory on a LSA engine doesn't make it a internal engine part...

Where did you find this guy????

btw whats the point of all this are you saying that everyone on a bolt on list with the ZL1 that have ported snouts should not be there???or ppl that put bigger diameter intakes then what comes from factory should not be there??
or same with throttle body?????

Victoryred1le · 12-01-2013, 02:19 PM

If you put a nick Williams 102 tb on your car, Is that not a bolt on? maybe this guy should just do that so it would shut everyone up. My company competes with redline so I know if Howard needs to he will put a stock one on and find power somewhere else so your argument is futile. I voted it a bolt on...because it is factory optimized equipment.

No, he is already on top of the list and wants to go faster.... but doesn't want anyone else calling foul....lol. Just do it!
