You said you were having a hard time surpassing 450Rwhp...? I don't see a cam and/or heads in here.

One thing to make life easier.. Switch to a nice merge... While you are at it I would switch to 1 7/8" headers.
nonono i never said I'm having trouble with my car reaching 450, i havent put it on dyno yet im prolly 330 or something.. no idea, jus guessing. I was referring to a few of my friends trying to hit 450 but they were always off by like 10 hp or something silly like that.

I believe mine are 1 7/8 headers, if they aren't I hear it does make a difference.
A merge is definitely in the works, but I'm highly considering a custom x w/ b4 axle dumps idk yet

yup. those numbers are way to low, but would cats & flows really rob that much HP if hes only making 450 with everything? he did have a fast 92/92 and a cam

my guess is its not tuned properly, or not tuned at all

and is it save for stock internals to be pushing that kind of HP?

A CAI kit, some bumper stickers, and a million LEDs.

But seriously, a well matched H/C combo with all the bolt-ons. Beyond that, without going FI, you could stroke the engine, and increase the compression ratio (which also improves gas mileage). FI: not necessary unless you want something that's extremely easy, and have the $ for it.

If you're thinking long term, stainless steel will last, 1 7/8. FAST is better than the LS6 intake, but costs more. Port the throttle body, do an X/H pipe, and a lid. See how that feels for power, then go for the stuff above

and is it save for stock internals to be pushing that kind of HP?
450, most likely no problem, but if the parts are already old, they may fail earlier than they would otherwise.

An intake is only as good as the heads allow it to be. He isn't gaining much with the fast.

Cats rob hp and depending on the flowmaster it could rob a lot or just a little.

I agree, I bought the car with this setup on it and was kind of confused as to why he didn't upgrade the heads when he did the cam... and everyone knows Flowmaster is a bad idea for LS motors. I think once I change the heads and exhaust, and re-tune I will be well over 400 without the nitrous. I have everything else already to get me there.

what is with you guys wanting to do a HVAC deleat to make 450 hp? thats just nonsense and its not going to net enouph HP to really be notice and if you want you could just deleate the A/C and keep the heat and get the same power results.

450HP is not hard to get, good seat of heads and a cam to match, got for a 11.1 compression atleast. Good intake setup and 1 7/8 headers with a good exaust system.

should be 450 and if your a little shy of 450 then get yourself a eletric water pump and underdrive pully and your good to go.

OP- you really want to know the easiest way to obtain a guaranteed 450whp without sacrificing any luxuries, drivability, etc. Its called a good supercharger kit and nice exhaust.

Yes, the stock LS1 shortblock is safe at 450whp.

Eh, couple different ways to look at it.

I can think of more reasons a street car that you want reliable with little to nothing changed with the idle/mpg/powerband/etc... Would be better off with nitrous than a snail or blower.
I have thought for a long, long, long time about all the pros and cons of all three for a true street car. Turbo was counted out very quick. Blower held its own in my eyes for a while but was counted out later on. Blower has all the pros of both with very, very few cons. The only con that I can think of that matters to myself, the power isn't there 24/7. However, for me.. I don't need the power unless I'm racing, otherwise I'm just BSing around and could care less.

And I'll take that name, I've been called worse!!

I think the main reason a supercharger is preferred for a street car is that there's no worries of running out of it, like running out of juice in the bottle.
But I see what you mean. Hints why my car already makes approx. 500hp N/A and is probably getting bottle feed strictly for the reasoning you mentioned, for racing. The thing is I don't drive my car a lot and I surely don't do much racing.

No doubt.

If I do go out for a night of racing however, I might get 5 run MAX... And thats if there is a whole lot of nice cars out.
I'm not stupid enough to go out with a bottle 1/4 empty, its not that expensive or hard to get it filled.
Chances of me being caught without enough giggle gas is slim to none. A 100 shot will last me a solid 10 sprays, more than enough for a full weekend of fun.

Plus... When you are door to door on the first run and then pull 8 lengths on the second run people are like WTF!?



Nitrous is it IMO.. I will own a procharger car in the future at some point because I have love for them both, but nitrous is hard to beat for many reasons.

Can you list your setup? And show your numbers? I also have full bolt ons and a TSP 228r and cannot get past 390 on my 99Z.

How about you list your complete mod list and i help you, your car has nothing to do woth anyone elses.

First, remember that an auto and dyno numbers mean nothing. It's all about the et that shows how an auto is performing. I make 377rwhp full weight and ran the times in sig barely spinning in 2200+da.

An autos first mod should be a converter, it is needed to get an auto run the expected time with any mods. They are dogs without a larger torque converter.
