my build thread, e30 with a 9 inch

[TheJuggernaut]

Ah crap, sorry to hear man. How come so long until the next day? Maybe another track? What if you get nomex underwear, can it be additive?

[MrBlonde]

Didn't get through tech. This time they told me that I didn't have the right jacket and pants. They said because I run E85 I need to have SFI 3.2A/15 rather than the normal 3.2A/5. When I got my chassis cert they told me that E85 counted as gasoline so /5 was good enough. As usual the rules depend on who you talk to. I didn't feel like making half passes so I got my money back and went home. The /15 jacket and pants are 1000 bucks so that's a pretty hard pill to swallow. I'm getting pretty tired of this.

The worst part is the next track day isn't till the end of September. I'm pretty bummed out about it.

I totally understand how you feel. Went on this journey back in 2004 with ANDRA (Australian NHRA) and the experience is almost identical. I can tell you that the pain does stop once you jump through enough of their hoops.

That 1.3x short time means you have a real opportunity for 8s in this bad boy, keep it up!

[Butters Stoch]

I thought the jacket was time thing ? Not a fuel thing !
I just had to buy one and when calling and reading the rules, mine is good to 10.0 said nothing about what fuel

[GT35Rm3]

You should be able to just get the underwear as an additive.

[someguy2800]

I have a confession.... I'm jelly of your back halved 9" setup, there I said it..
Hope you hit 9's Perry..!!!!!!

I'll have it in the bag if they will just let me run the car! It's an animal at 28 lbs. I thought about just running anyway and letting them kick me out, but I don't want to do it that way.

Nope, it's not additive. Here is the line from the book. Prior to 2012 this was only applicable to methanol. I wasn't aware they redefined it and neither was the guy who certified the chassis when I asked him about it.

9.99 and faster, any vehicle, supercharged or turbochargedwith alcohol: Suit meeting SFI Spec 3.2A/15, gloves and bootsmeeting SFI Spec 3.3/5 mandatory.

i that's going to take either an auto or a couple hundred more hp but I'll get there someday. It's definitely got more in it for 60 foot. I think it will go 1.2x on the stick with more tuning

Doesn't matter above 10.0

That would be nice, I can think of better things to do with $1000

[bubela]

a 1.2 '60? *sigh*

[hsvturbo]

Why not go $10/gal rAce gas for the drags? Tuning isn't an issue for you. Then go back on e85 for the street.

I considered that but at my compression I would need something like q16 or vp import. In the long run the jacket will be cheaper. I also considered changing pistons, but I want the car to be the way I want it rather than letting the rule book change up the whole program.

Go to your local embroidery shop. Have them make you a patch.
$30-50 custom patch + $60 jacket = $1000 jacket ; )

[rajicase]

^^lol :d

I got my magic clothes in the mail. Most expensive clothes I will ever own lol. I can't wait to wear my $1100 snow suit in my 100 degree race car. Quality is very very nice. By far the nicest fire gear I've had yet. RJS racing is the best and are great to deal with. This was custom made to my dimensions and it only took a week. When I called the president of the company answered the phone. 100% made in Michigan.

[Butters Stoch]

That's great. Now what flea market sells knock off's for $60 ?

[someguy2800]

Just do what I should have done. If they ask what fuel is in the car say race gas. I bet they would have never questioned it. I get scrutinized pretty good because the test and tune events we have here are nhra bracket events. We don't have track rentals like you east coast guys do.

I highly approve!

For gloves, make sure they go well past the wristband on the jacket. I've got a burn scar on my right wrist from a gap between the glove and the fire suit sleeve....

Picked up a th400 from the junkyard today. This came out of a 87 GMC 1 ton van. I paid $175 for it and was told it worked, not that it really matters. I paid a couple bucks more for this one than some I have seen on Craigslist because this one is an HD case, which was used in motorhomes and delivery vans and the like. Some say it makes no difference from a standard case and others say its best to use these for builds over 1000 crank hp.



This one is also a long tailhousing which should allow me to keep my driveshaft loop where it is and possibly the same length driveshaft as the T56 magnum.

Out of curiosity here is the physical size compared to a M20 5 speed. The gear case of both is pretty much exactly the same size. Of course the oil pan rail is much wider. Interested to see how much if any work the tunnel will need to fit it. I know a local guy who is building an E36 with a nitrous ls motor and a th400 and he told me it fit just fine in the E36 but I know an E36 tunnel is a little bigger than an E30. ive seen people do LS1 4l60e swaps in E30s and those are just as wide as a th400 so I don't think it will be a big deal.




with both propped up to the same input/output height the G260 is slightly taller. about an inch toward the front and 1 1/2 toward the back.



here is a picture of my T56 next to the same e30 5 speed.

[3literheater]

So are you selling the magnum now?

[someguy2800]

I will be sometime in October. I am going to finish out the season. There are a few people interested.

[pbonsalb]

Are the people using the big bellhousing autos mating them to V8 that are mounted further forward so the front of the bell can stick out of the tunnel further into the engine compartment?

Too tired to write about it but went to the local Wednesday night no prep event. Something is very wrong with the new drag radials. It shakes violently over 130 mph and the car is nearly undrivable. Second pass I pedaled in third and forth and got out of it a couple hundred feet before the traps and went 9.88 @ 143. I played with the tire pressure and shocks but it just kept getting worse. Ran I think 6 passes, all of them were 10.0 to 10.1. The traction is much better on the Hoosiers buts it's unsafe to drive over 120

[futureroadracer]

Are you running bead locks/ screws?

[someguy2800]

okay here is the rundown. Been having problems with my pickup so it's been a very hectic week. Front driveshaft when out this weekend so I spent all night on Monday taking the u joints apart only to find the alignment bearing was junk and it needs a new shaft. Then I was going to pick up my kid from the grandparents and got a huge bulge in one of my tires for the 3rd time. (don't buy treadwright tires) This happens every time I'm going on a big trip so I finally had enough and went and got a new set of toyo's.



The racetrack crew is always complaining to me that my car dumps water ou the exhaust every time I launch so I built a new exhaust for the car. My old exhaust was aluminum from the downpipe back which is known to condense a lot of water due to how fast it dissipates heat. I can't stand driving it with no exhaust so I decided to take the weight hit and build a new 4" exhaust with parts and pieces I had in the shop. I also extended to end of the downpipe to turn 90 degrees under the car. The old downpipe ended with a 45 pointed at the ground.



I finished that last week but didn't get to making new mounts because of my truck until Tuesday night. Before I had it solid mounted to one of the seat harness studs sticking through the floor but this puts a lot of resonant vibration into the floor. I made a new mount out of stainless with rubber discs that mount to the rear frame crossmember. It really reduced the highway droning in the car. Didn't finish that till 4am yesterday.



Next issue to address, I have been turning up the boost lately and I am totally out of injector. At 60 psi base pressure and 28 lbs of boost I was at 100 duty cycle on the injectors and low 12's AFR. Shopping for bigger injectors I found some 2200cc Bosch natural gas injectors on eBay. I've never seen this exact injector before and was not able to find any info on anybody else running them but decided to take a chance on them. I paid $540 for 6 of them on eBay but the seller has since Increased the price by two and a half times for some reason. If they are real Bosch I'm sure they can be had for much cheaper from another Bosch dealer. I haven't been able to find any info on them from Bosch either so they very well be a counterfeit chineas injector. They sell these on Alibaba too, so who really knows?

http://m.ebay.com/itm/Qty-8-Bosch-02...-/172232435451

They are a mid length injector so the need a height adapter and like all ev14 injectors they need a spacer on the bottom to keep them from seating too far into the manifold.





The plan was to get the injectors on Tuesday and then bench test them to see how they flow and figure out the offset. That never happened because I didn't get them till 3pm yesterday and the race starts at 5. I really had my heart set on running 30 lbs of boost so I put them in and figured I would see if I can retune the car in the way there. I turned the pressure down to 40 psi and reset the injector size inmegasquirt and it ran pegged at 9:1 AFR with fuel dumping ou the exhaust. I ended up having to take nearly 50% of the fuel out of the idle and part throttle areas of the map. After 10 minutes in the garage I had it running okay and the accel enrichment in the ballpark so I put the old injectors in the car just in case and headed to the track. Drove for 5 minutes to let the O2 correction do its thing and made one pull on it to see where it was in boost. It was much closer under boost so I just had to pull a some fuel up top and smooth out the part throttle again and it was okay. I think I set a world record for tuning a car lol.

Got to the track and set the tired to 16 psi, boost to 25 lbs and made a pass. Launch was really good and the track was okay for a now prep event but the tires started shaking hard and I got out of it at about 1000 ft and ran 10.09 @ 133. Next pass no changes and it shook hard again. I pedaled in 4th to try and calm it down and got out of it again a couple hundred feet early and ran 9.88 @ 142.29. Next pass I raised the pressure to 18 no change, pedaled and ran 10.1. Then I pealed all the wheel weights off the rims but didn't help, 10.1. Raised tire pressure to 21 psi, I spun hard at the top of first but ran it through anyway and tried to drive through the shake and ran 10.something @ 145. Last pass I turned the shocks way up to see if that helped but the car went straight to the rev limiter in 1st and 2nd. At that point I decided the car was not safe to drive so I parked it and watched. I had top ET of the night but another guy in a turbo LS Nissan had top trap speed.

Gotta call Hoosier about the tires. I put it on the jack stands this morning and both are way out of round. Fun times.

. No I was told not to run screws

[NOTORIOUS VR]

The 2200 cc bosch's are the same injector ID and others use from what I understand... just you're not getting a dynamically matched set which is awesome when dealing with such large nozzles.

EDIT: my bad... I believe they use Bosch PN: 0280158821

Not sure about the ones you have.
