Whoa, whoa, whoa the dude was posting his results, give him a break. You expect him to hit 10s off the trailer or something? Why not give advice on how to make adjustments with the S300 instead of babbling about his driving skills? I'm sure as experienced track racer you are, you should be able to give him some pointers instead of pointing out the obvious.

Turbo Bseries, what is the highest you have tried launching? 4K? are u full throttling it or part throttle? Do u just dump the clutch or feather it? Are u preloading with the E-brake?

Fine tuning pre-loading the drivetrain will definitely help. It's a bit hard on the clutch and flywheel though. However getting the launch perfected in general is what makes the difference. There's a fine line between bogging and spinning. If you can flirt with that line, get the car to hook, stay straight, and don't botch a shift then you will definitely get faster and more consistent.

Just remember stock axles don't like hard launches on slicks. Granted snapping an axle is much better than breaking a transmission. I've always looked at axles like the drivetrains circuit breakers lol.

Lol that's funny about the axles. And yea my stock Axles took precisely three 1/4 mile passes on sticky tires and hard launches to give out. Of course that was with lots of abuse on all seasons too. But after the DSS 2.9 axles and some fine tuning with my boost by gear and my left foot, I was able to eventually get 450whp down the track reliably back to back to back and cut nice 60' times on just some small 205/50/15 NT01 drag radials.

Great numbers Hugato2002, I wish I had easy access to E85.. we have same build I just have a stock head, thinking of building it and making more then what I make now(317whp)... BTW how far are you revving the engine?

LightningTeg

Pretty solid.

I think some 404's would work better with that combo. The 402ts are geared more towards the mid range, but the victor x intake is not.

HUGATO2002

8200rpm

HUGATO2002

Thanks. You're right. I got the 402s for the low thats y. My next step will be lsv. What tires would you recommend for now until im able to go bbg?

You guys are mostly on stock ignitions too right? Im helping a local friend with his built B20. Its all quality parts and he just had it tuned and it pulls great but loses power from 6-7k, but its fine everywhere else. When he first told me, i assumed the tune was bad, but he says the tuner and another Honda technician both told him its because he needs bigger plug wires and stronger aftermarkrt dizzy. I dont known if i necessarily believe this though because ive used stock parts on some pretty stout boosted setups before and this is just a high comp all motor setup under 250whp. Any input? Ill be looking at the car in person Sat to hopefully give him the true diagnosis but any help is appreciated
.

LightningTeg

No something else is up. Grab some new OEM NGK wires, the correct plugs and make sure the coil and ignitor are good. Stock ignition is good to 500whp +. Hell I have a friend up here running 800whp on the stock Dizzy.

HUGATO2002

My Ls is making 466whp at 22psi and 500whp at 25psi with oem dizzy and ngk plugs and wires.

VegaS10

Huga, do you have any pics of your manifold?

We've got very similar setups.

B20VtecVillain

I think something else is definately up too. It's a 12:1 B20 with built GSR head, Pro1s, tuned on Hondata s300 by Chris Miller is what he said, but it's on stock injectors/rail/regulator etc and a 255 wall to. I asked him to send me the dyno run files from the tune so I can see what's going on with the AFRs when it drops off but I haven't gotten them yet. I'm thinking of the stock dizzy/wires/plugs etc are all in good order then it might be a tune or fuel issue. Something tells me this thing is needing way more fuel up top then stock injectors and regulator can provide, but if it's truly Chris Miller tuned you would think he would have advised him of that fact and not said hey you need better Dizzy/wires or a MSD and COP if you wanna spend the $$. Stock ignition is fine at his level, stock injectors not so much.

slowDB7

Im not an expert on this stuff, just here to learn.

But im gonna guess he should upgrade to some bigger injectors

B20VtecVillain

Yup lol. I'd recommend 310cc minimum.

Stock injectors are his problem. Like, a massive problem. Whatever tuner told him that his ignition was his problem is an idiot.

You uh, might want to check what section you're in. And what thread you're in. This is the LS build thread, in the FI section. Your NA LS-VTEC motor doesn't fit here at all.

Turbo Bseries

currently only revving my engine to 7500rpms, build bottom end, stock head.. made 317whp at 15psi garret 60trim.. I want to add Crower stage 2 turbo cams and dual valve springs and retainers.. and raise the pressure 3 or 4 psi.. just trying to make a good 360whp or close(on 93 pump gas)... or should i just add a vtec head? i think on a build the ls head i can rev to 8krpm and make my goal..

Asking because a guy that lives 2 hours from here is selling a gsr head with supertech springs, retainers and valves and adjustable cam gears for 350.. head looks clean on the pictures and i think the price is great.. but something tells me to just stick to the LS and not get involve with vtec..
