Custom T.S. T4 Manifold and front end

SIM TSI LAUNCH - YouTube

Working on the tune. So far 23 psi by 4800 rpms. I believe I was just streaming the log when I recorded that and I don't have 3rd gear roll ons.

Sweet glad to see her almost done.

Why didnt you run? Did you pass tech?

 

[viperlp01]

I ran twice. My starter bolts stripped out somehow and I really didn't want to rip down one of the 2gs that came with us to make more passes. I went 11.6 @ 128 first pass and 11.3@ 132 the 2nd pass.

I need to make a front motor mount. The 1-2 shift is extremely difficult.

11.3 @ 132 is pretty impressive. Thats shittin an gettin son.

 

[viperlp01]

Theres the log for guys with link.

Are you on pump gas? if not add some timming, 16ish for 100+oct and 20+for e85. Im having a problem with my frontend build, Every time I reread the nhra rule book I see something diffrent. I knew that Tech would pass you. I didnt go to the shootout but a buddy took pics for me and gave me mis-information about your car.

For you motor mounts, Take some solid steel plate and weld it on both sides of your rear motor mount. It will stiffen everthing up but by having rubber side mounts you will still have enough give so you wont destroy your trans. Thats how I have ran mine for over a year now.

I disabled my knock sensor so I could make power for this event. I talked with some other tuners there about my stroker set up and they say single digit timing for a stroker. I am going to be messing with some things that they said to see if they work. Other than that I was happy.

I have been at a more official tech when I went to a TnT on Wednesday and the only thing I got shit about was I did not have a metal shield on the bottom of my fuel cell.

what did you do for the rear mount?

 

[99gst_racer]

I'm pretty sure his rear one is stock. I'll bet the issue would be eliminated with a solid aluminum rear roll stop.

Congrats on the 11.3 at the SO, John.

well the main problem isnt the lack of a front motor mount, the problem is a stock rear motor mount.

I had a couple people switch from solid aluminum roll stops to my polyurethane ones.

The engine actually lifts out of the engine bay. My crankcase evac ports are on the top of the valve cover and before I raced I only wore a mark in my hood in the front fitting and after the 2 pulls my rear fitting has worn a spot

 

[99gst_racer]

That's typical engine roll. The rear fitting is wearing more because as the engine rolls forward, it brings the rear of the VC sligthly closer to the hood. Like I said, slap on a solid rear roll stop, and it will take away the majority of that roll.

Sept 2 I will be running at Midnight madness and I might go to the track before then. I have to fix some small tech stuff and make myself a front motor mount if the rear solid doesn't do enough for the 1-2 shift. I talked to Jeff Bush about the front motor mount situation and he said before he put one in when he stalled his engine up to launch the engine would lift 4 inches out of the engine bay. That caused drivetrain issues. Hopefully With a more solidly mounted engine I can run 10s on some worn RA1 Toyos and maybe trap alittle higher if I turn the boost up.

You need to make one piece/solid motor mounts that attach directly to the frame and then to the engine. With out the the front frail rails and radiator support (even though they are flimsy and light at best) they box the front end up and reduce twisting during launch. And with out the lower subframe support tying everything together that does not help either. The engine actually needs to become a structure part of the chassis, (kinda like F1 cars )

Just guessing from your gnarly front end in your avatar you have had experience with tying the front end together. Do you have any pics you can send me of what you did to the mounts?

 

[viperlp01]

Well I am going to start making VERY solid mounts for the engine this week. I am also going to make some other stuff better. The seat bracket I made makes me sit very high. I need to bring it down. I need to fix my starter. I need to move the knock sensor.

Does anyone have any videos of either of my runs from Saturday. I had 2 people with cameras and both some how failed to get a decent video.

 

[dmc]

Dude, that's one very impressive build you got going on there!!!! I am really impressed at your ability and the speed you got everything completed in!!! Really is one sick car you got there, love the custom fab work!! Keep up the great work, keep the pic's and the videos coming, and update us on what up do with the motor mount situation and any other projects you decide to tackle. Oh and that mani looks great, welds are great looking, screw all those haters, there ####en everywhere, losers

 

[viperlp01]

Hey thanks man. I think I am going to be selling the RPF1's. Either a Motegi tracklite or a Rota slipstream in a 15 paired with a 26in Hoosier QTP .

Regardless I will try to hit 10s this friday. I am going to lower the tire pressure on these toyo RA1s. I am loosing traction on the street with this tire combo just rolling on it. I am turning the boost up today or tomorrow and get the timing right. I think 30psi should net me high 130 traps which I HOPE gets me that 10 sec slip and a boot out of the track for no cage.

 

[99gst_racer]

You wanna borrow my slicks this Friday?
If so, I'll throw them in the back of the Suburban. Just bring a jack and a tire iron and we'll swap them out when we get there.

 

[viperlp01]

Hell ya Paul. I will bring a spare axle as well.. We are taking the trailer so I will have plenty of tools. I am thinking about being there around 7. Let me know man.

 

[99gst_racer]

I'll be there around 7 as well. I guess we'll find out for sure how well the 15" Traklites clear your brakes.

 

[viperlp01]

Ya no lie

 

[viperlp01]

Put Pauls slicks on last night and track conditions were far from favorable for a night event not counting HIGH humidity and temps. First pass was at 25 psi and I went 11.22@ 128. So we threw on a MBC and turned it up to 30 psi. First pass at 30psi had 10s written all over it but half way threw 3rd I blew a vacuum line off so I rolled to a 11.7 @100. Last pass of the night I launched the car and hopped all over the place as I spun and broke my rear diff. Pulled my diff today and welded it. Trans will be coming out this week to get a welded center and hopefully the added traction will get me the 10.

 

[viperlp01]

Well here are some pics of the welded center I did.
