So I just got my motor back together

Built GSR
ITR head
s2 valve train
s2 IM/TB
2.5" IC piping
12" FMIC
OBX top mount
tial 40mm wastegate
4" DP
T3/T4 .70/.68
@14-15 psi
Tuned on Neptune by Matt Shue

22x8x13 Lenso/MH combo (10-11 psi of air)
Hydro B16/ITR final drive
Quaife LSD
Stock axles

Went out to the track this past Friday for the opening, it was about 80-85 degrees out. First few passes I wasnt letting the car build enough boost off the line with the antilag and it kept falling on its face at launch. I finally got it to build about 10-12psi off the antilang launching at about 6500-6700. Car spun a little then hooked and before I would get to the end of the track I would run out of 4th gear for maybe a sec it felt like. Im using the small 22" slicks with the b16 tranny and revving to 8700-8800. Just looking for any suggestions on how to make it faster as it sits.

<U>Pass 1:</U> Bogging off launch, bouncing off rev limiter in 4th (8800)
2.0136---60 FT
5.7111---3330 FT
8.5592---1/8 ET
86.79----1/8 MPH
12.964-- 1/4 ET
111.01---1/4 MPH

<U>Pass 2:</U> - Miss 3rd gear, bouncing off rev limiter in 4th
1.8005--- 60 FT
5.3225--- 330 FT
8.2602--- 1/8 ET
85.18 --- 1/8 MPH
12.638--- 1/4 ET
113.96--- 1/4 MPH

<U>Pass 3:</U> - Launch felt perfect, bounced off rev limiter in 4th (8800)
1.9062--- 60 FT
5.3088--- 330 FT
8.0039--- 1/8 ET
90.74--- 1/8 MPH
12.301---1/4 ET
112.50---1/4 MPH





*UPDATE*

ran last night car went 12.0 @ 114.5 on 22" slicks with a 1.7 60ft shifting into 5th


Dont have time slip in front of me but what I remember is
1.72 --60ft
5.0x ---330ft
7.7x ---1/8 ET
91.x ---1/8 MPH
12.00 --1/4 ET
114.5 --1/4MPH

will edit when I get home to correct whatever is wrong.

I just cant understand why people wont shift into 5th if they have plenty of time to do it and pick MPH up. Its like shifting to any other gear.

I could understand if you ran out of gear 10 ft before the line but this is totally different.

I would like to say that car makes at LEAST 350whp but probably more and its only trapping 113 because you dont want to shift.

I give you a thumbs up for going with Shue for tuning.

 

I think im going to go back this friday and hope for an 11 sec pass on the same setup and work on my 60 ft, as well as shift into 5th.

 

i had a very very similar setup on hondata s200b (might have been s100), only a ramhorn instead and 3" dp/exhaust. making 360whp at 12-14psi. same b16 tranny with quaife.

i was using 24.5mh slick not having to shift into fourth of course with the bigger slick, shifting every gear around 8250-8300 and going through the traps in 4th gear at 8400. it would run constant 11.20's in a 2350 lb. 97 hatch. this was getting 1.73-1.78 60fts. i wasnt afraid of shifting into fifth, just didnt have to.

i would think you should/could be somewhere around the same times as that. maybe try a bigger slick...

Good luck, im sure you'll get it.

BTW try a little less tire pressure in the slicks.

When I wasnt running an anti-lag and just launching on rpm and load id run up to 15 psi in them and pull 1.70's

Now that Im building boost and have about 100 more whp i dropped down to 8-9psi and pulled a couple 1.68's open diff.
23x8x13's

 

are you babying it?

 

no im not babying it I could prolly shift a tad bit faster but I think keeping it in 4th is killing my time and mph

 

when i used to run my SI i would runn 6-8psi in my 24.5inch slicks! and they hooked putting down 500whp and broke DSS stage3 axles! never ran out of fourth gear in my b16 tranny though! ohh yea and it looked like you were doing a 1st gear burn out if so try a second gear from the two step!

 

last pass I did a small 2nd gear burnout but didnt do it for long enough

 

Judging by your 60ft I don't think your preloading. Bring that 60 down and you'll definitely shave some et. Your definitely running too much air pressure. I run 6.5 in my lenso's. and why does that look like an ebay turbo?

 

cause it is, I think he found another crack in his manifold too.. keep trying marcus , you will get it !

Im preloading so I less the chances of breaking an axle. Ill be at it again this weekend hopefully for a 11 sec pass with a better 60ft.

 

My car is right on the brink of shifting into 5th . . . Sometimes i do ,sometimes i dont.

My fastest times are when i shift into 5th fwiw

 

ok im going to try shifting into 5th

 

work on them 60ft times, buy some bigger slicks, and work on getting a new mani.

 

When you say you couldn't get the antilag to build enough boost, do you mean you just weren't setting the launch limit high enough?

 

i mean i wouldnt start revving it until the other person was staged and it takes like at least 3-4 secs to build like 10-12 psi. I would only get it up to like 4-5psi because i didnt have enough time to rev it for longer

 

You just need more seat time to get used to the new setup. by the way you like my new avatar??

 

ha ha

Step up to 24"s, homie. Less tire psi. You're only a tenth away now!

If you looking to get rid of them 22" MH's and Lenzos, PM me...

 

BTW, your boy's blue EG hatch is SICK! I ended up leaving at 9:30.

 

yeah a set of taller slicks would be your best answer than shifting into 5th. i was fighting the same thing with a stock ls w/gsr tranny on nitrous. just used a taller set of tires and knocked off 3 tenths.

believe me ive been in your shoes, listen to everyone and get some slicks...youll be running mid 11's at least

 

yea im going to go with some 24.5 because Ill definately need them on high boost. Im going to a different track this friday so maybe I can get the 11.9
