Stock LSA 800hp what will it take???

[Breink_7]

First post on here so I’ll give a quick run down,
2014 ZL1 M6
Car bone stock made 501rwhp base line then 540rwhp w/ tune
Current mods:
- Fore Inn. dual pump return fuel system w/flex fuel (always run 100% E85)
- I.D. 1050’s
- 2.45 upper
- rotofab intake

Car made 685RWHP on current setup above. This winter I plan on doing the following mods:
- Afco HX w/ 5 gallon ice box
- lower pulley (don’t know what size yet maybe 9.10?)

Now for my question... I know most of you will shoot me down and say no way but I figured I’d see what you all think. I think it would be fun to see how big of numbers I can get out of it without getting into the motor (Stock cam, heads, blower) I figure if I put a lower pulley w/ the ice box I should be able to get up over 700rwhp pretty easly now this is where I’m not sure where to go with it. Should I get a 102 TB and match port the snout? Or do I go all out and port the blower and everything but would it be worth it with out the cam and headers? Trying to see how close to 800rwhp I can get without having to get into the motor. What are your thoughts and what direction and mods would you go with to reach this goal?

I appreciate the input and opinions you guys have very curious to see what you guys think.

Well I have a similar setup to u but a 18%. Plus headers and full exhaust. And I’m only at 670rwhp. I can’t see u getting to 800 without quit abut more. But I suppose if u tell ur tuner that’s what u want he can show u a graph w 800. There are different dynos out there. I’d like to know what kind ur car was put on for those numbers

[silversleeper]

685hp seemed high to me too but considering your numbers it might be possible without the SAE vs STD dyno tricks.
I think his 23% over your 18% would nearly equal out your headers.
He has a manual trans which would give him what, 15hp over our automatics?
That would put him right at 685 then.


Op pully it up and put on a
AEM V2 Water / Methanol Injection Kit

I want to see what it would do so we might follow your lead.

There's no way you're getting to 800 RWHP without full Heads/Cam/Ported Blower/Meth/E85 or both. Even then, not everybody gets there. You'll need a max effort setup. Look up Race Proven Motorsports' video on their ~822 RWHP ZL1.

You'll need:
2.45 + 18% (This is a very aggressive pulley combo. Will create lots of heat.)
5" RPM Intake, TB preferably
Ported Blower and Snout
Heads/Cam
Preferably Meth or E.
Fore Fuel System

Have fun.

Went and found the video for ya...

Yes I know 800hp is not going to happen, I just want to see how far into the 700’s I can get I’m thinking I might be able to get close to 750 but hell I could be maxed out where I’m at currently idk.

Silversleeper I thought about the meth with E85 I’m just not sure if I trust the meth kits enough yet I’ve seen some bad stuff happen with that stuff and makes me nervous that’s why I’m leaning more towards the ice box and HX.

I do think there is power to be gained tho just with getting rid of some of the heat for sure so we’ll see, I’ll throw a lower on it cool it off and maybe do a 102 and see what happens it’s not gonna hurt plus it’ll be a step in the right direction for once I do cam it I suppose lol

I going to jump in and say that you need to work on letting some of that boost pressure out. Without headers and or a cam, adding more boost is pointless because the blower is just no longer efficient and just generating a TON of heat. I am guessing you are around 15 PSI or so now and based on my experience there is little more to be had with the LSA blower and be efficient. 800 RWHP starts to approach the reliability limits of the internal components. Not to say it wont live, but how long will it live. You will need heads and cam to get there, maybe a ported blower, but it can be done.



Mods don't just add fixed HP per component. They have to work together and give you a more efficient engine.



I have never been a fan of dyno numbers other than the before and after gains on the same dyno corrected to SAE in close to the same conditions. I personally look toward 1/4 trap speed to see what kind of power I am making.

Bingo.

I agree with crazydave and Can'tHave on this. They know there stuff.

Crazydave is right about the headers. Throwing the pulley in without headers will be counter productive. There is no where for the added pressure to go and makes it incredibly inefficient and hot... therefore dangerous for the SC. You are going to get to a point where the heat you are generating is countering the HP you are going for. I will add, I REALLY REALLY regret not ceramic coating my headers. If you get them go that route.

Personally, I am sitting at 764rwhp. To get there I had to do a cam and pushrods etc. I did a lot of cooling to the car last winter and drove it all summer with the mods that I did... never had a heat scare and IAT and IAT2's were always within 15* of each other. I have a black car and it gets well into the 100's in ID. Only thing that I have is some tuning issues since there isn't a good tuner within 300 miles of Boise. I am not going any higher than where I am at because I am not wanting to get deeper into the internals. No meth, no ice tank but HX with fans, coolant res, crank case breather, cam and e85. I trust the set up and multiple people in the forums have had success with this set up.

What heads are you running? These are some pretty stout numbers. What dyno was it tuned on?

I've been watching this thread for a minute. The LSA bottom will live at 750 rwhp for a while on blower only (no nitrous). Anything above that at higher than recommended boost levels is asking for trouble. Your tuner is the key in this territory and how long you are WOT (1/4, 1/2, mile events).

Mine started to have blow by issues at 783 rwhp on just a 2.55 upper pulley and full bolt-ons, E-85/Meth. Car still ran strong but compression was low on 1 cylinder (blow by). Worn factory rings coatings was culprit. This is a known but not mentioned too often issue in the LSA/LS9. Currently on forged bottom with factory crank pushing 850 rwhp with basically the same combo. Just more boost, 5" intake and 102 TB.

Hope this helps.

Fixed it. Bet that thing is nasty!

It takes a bit more to get there in an everyday usable pkg.
