I have seen some builds that are getting to those levels on the stock blower, how can this be done? I have aftermarket heads, 102TB, big cam, etc, etc but I am not anywhere those numbers.

ported blower, ported lpe snout out to a 108, 108 tb, 5" intake with big filter, big cam, after market heads with oversized valves full exhaust and a very effecient cooling system flexfuel and a generous dyno

I have the blower ported aswell as the snout to 102mm, my heads have oversized valves and the cam I am using is a comp cams 477, 2" long tube headers no cats, 2.35 upper and 14% damper. Keeping good IAT2 temperatures with meth. Posting my dyno numbers tomorrow I am running a 100hp shot but looking on the big number without nitrous.

What are you making? I'm running a 102 tb 4" lpe intake ported lpe snout and blower custom grind, 234 247 .628 .638 on a 117 if I recall right. 2" kooks catless x akra mufflers and a 200 shot through some spray bars. It made 752/750 in Phoenix 110 degree heat on e85 making 18 lbs. now that I got it back home I. Washington with better air and temps it's see if 21.5 typically. I haven't thrown it back on the dyno yet but I suspect it's probably making low 8xx now on blower only. And mid 1xxx or close to 1100 on the 200 hit. Debating upping to a 300 and seeing how she does.

Let us know how it runs when you have the 300 shot on . I haven't even driven my car with the power it's going to have soon and I already want to get nitrous... You are a bad influence lol.

Morphin

What is the biggest shot the stock fuel system can handle? I am going to the dyno today to get the new numbers and will post them.

ace32x

I have a standalone fuel cell/ system for the nitrous so I couldn't tell you :/

I always wondered why you guys just dont simply ditch the blower to go Twins turbos?? It seem sooo much more easier to make 1***WHP on pump with turbos!!!

ace32x

Money, I'm younger and on a budget lol. I could probably pull the blower and sell it but I don't want the car down in the meantime

timmyZ06

Well I'm sure full bolts cost just as much as tt kit!

Ballbearingturbo

You are correct. I def could have put TT kit on for what I've spent for 9xx rwhp.

ace32x

Only kit I would run is a ttix kit and I'm into my whole set up less than that kit including install. So that kit and install would have ran me another 2500-4k I like the pd blowers personally less hastle with maitence and scavenge pumps if the kit has one and blown off couplers and turbo seals etc. They're just such a pita

timmyZ06

But Turbos is MUCCHH more effeicent though! I could only imagine how crazy that would be on a LS9!

This has been discussed before! People don't TT ZR1s for a few simple reasons.

1) it's going to set you back about 20k for a decent turbo kit installed and tuned. It's going to need to be custom to get much more power than the blower (with a little n2o) can do. The corvette also isn't exactly the most turbo friendly car in the first place....
2) not many people are going to want to rip into a 100k car to remove one of the unique features of the car (the supercharger).
3) it's MUCH more cost effective to get a Z06 and TT that.

I have not doubt that the engine would make a **** ton of power with the blower removed and a set if twin bolted on. However I can't see the point when there are easier, more cost effective options out there (Z06).

timmyZ06

I disagree, if we take 2 bone stock ZR1. 1-blower full bolts WITHOUT N02 2- completely stock motor with a nice TT setup. TT will likely end up cost less with a TTix turbos kit with 3"downpipe and make MUCH more power on pump. ZR1 to me is much more than a blower, i don't mind take it of and besides i always loved how turbos feels. LS9 will be more efficient with turbos and just stupid power level!!

ace32x

Your mistaken. I quoted this out as ttix is about 8 miles from my house. Ported stock heads ported blower and lpe snout exhaust cam and n20 is cheaper by 2500-4k

Actually I'm wondring about why can't we see BIG HP LS9?
Why there is no good numbers on the mile, half mile or even 1/4 mile! while other cars put some serious records?

chuntington101

Simples, the supercharger is the limiting factor! Also the design of the inlet isn't the best for flow. Great for packaging though. You think a classic supercharger would have the whole of the face of the rotors open to the airflow. The mustang guys use massive throttle bodies to help reduce restriction. With the LS9 supercharger you just can't do that.

If some came up with a whipple 4.0/4.5 kit you could probably see power into the 1000rwhp zone as the SC would have sufficient capacity.

I would love to see you, and I mean this honestly, get a ZR1 TT'ed but it will cost over 20k all in and the TTix isn't really the best solution on the market. The packaging is very tight (you need to machine down you engine mounts for starters) and I think the pipe routing could be better (you used to loose brake ducts).

In my opinion the ZR1 really deserves better and should be using something like Nick Yoskin's Bam Bam kit (if you can get him to build you one). The DKT APS copy also looks good but you still have low slung boost pipes that sit under the front cradle. There are a lot of custom kits out there (vengeance is one that springs to mind) but it's finding one that meets your needs.

The corvette isn't an easy car to turbo charge mainly due to space but also cooling as well (massively air restricted compared to say a gen 5 Camaro). Hence why there isn't a single 'style' of twin turbo kit.
