1800 wow that sounds too light, i thought stock they weighed 2800

[ma.racing]

mine was 2400 stock the s14s may be heaver but my s13 fully striped was 1800 with the ka24 in it and the ls1 is lighter

With a stock LM7 aside from the mods listed , what would you guys think would be the maximum WHP output on race gas with what ever turbo set up...

racegas is not needed. Meth is optional, i have it but hasnt been a factor in any of my HP figures or my times. My IATs are cool just on 93 octane. Tune is key part of it, so is effiecency of the combo, cool motor temps

as for HP. its more then you could handle at the moment. any of the LS motors have enough potential to get a RCSB into the 10s with a good 60'

Alright I want to thank everyone for the help thus far.

I am now leaning towards a front mount turbo set up, I have seen people talk about Exhaust housing on front mount turbo set ups vs. rear mount turbo set ups. Does anyone have any info on that?

[ma.racing]

what you mean

[SLO TRUCK]

its all about how its set up and your tune

This isn't totally accurate. Yes the Tune is very important but also specing out the right turbo for you need and wants is just as important.

not if you go rear mound and you have all 8cyl pushing it

Rear mount is gonna lag more than a front mount all day.

How much lag do people usually see with this size turbo on a LM7?

I have a MP70 on a 4.8 with a small cam. I start to see boost around 3200RPMs
