MY Real Street 275 build
#882
I am not an extremely religious person in the sense of going to church every single Sunday, but I am a spiritual person that believes in a higher power.
I always say a quick prayer right before I belt in and get ready to go down track. He was definitely watching out for me Saturday, that's for sure.
I also have my tribute to my late Father on the car as well, and I always feel confident in knowing he's with me when I take off down track. We always wanted to build a race car and never got to do it. I know he is enjoying it as much as I am right now.

When I got the text you hit the wall I expected the worse but glad you came out as good as you did and once I seen the pics of the car and heard ya went back out and finished the day I figured all was good. Looks like the worst damage to fix will be right behind the door. Get to check it out anymore?

5.14@137.50 this weekend.
Made it to the third round out of 28 cars qualified at Holcomb Spring Nationals.
1.21 60', 3.36 330' 5.14 660' 1.78 back split so it's legit!
I still have a 2 tenths delay in the second stage of boost and I'm hoping the tenth we need to knock out of the 330' and E.T. will come from there. Just have to make another slight suspension adjustment and keep chipping away.
This was also at 3290# race weight which is 40# above my minimum weight.

had the exact same thing happen to me, set screw loosened causing the steering shaft to slide down and I had no idea till I tried to slow down, rode the left wall till it stopped, went back to the pit fixed it and kept racing

Strange disc brakes.
Yep, crap happens when racing that's for sure!!! The guy that makes the least amount of mistakes will usually always win!
Took the car to Piedmont Dragway this weekend to a True Street 275 race. Our local Horsepower Junkies forum sponsors a semi annual race called "Dragging Rights" each year and the True Street class has been the highlight just about every year as far as I can remember.
After raising the ride height up last race, I decided to try raising it up some more. I think the COG (center of gravity) is right where it needs to be in the car (at least for now) and I'm finally hitting the tire like I've always wanted to see the car hit it.
We qualified number 1 at the end of the first round on a hot track (120+ degrees) with a 5.16@138.41. 1.26 60' and 3.38 to the 330'. Going up for Q2 I put a little more to it and went a 1.23 60', but drove left out of the groove and had to lift. Our 5.16 hit was still good enough for number 3 with number one being a 5.11 and number two a 5.13. With the 1.23 60' I had and with some added power I found out the back I know we had a 5.10-5.11 in it, but didn't get to show our hand.
E1 the car still drove left, so Jonathan had me re-adjust the ride height again and we got it close enough to make E2 where we lost by .0015! I cut a .075 light to my opponents .136 and was off to the races. Car started to power wheelie and drift left(not as badly) and I had to lift twice to keep it straight. While I was literally driving the crap out of the car I missed my shift point by 800rpm. Poor engine literally had its tongue hanging out at 7700rpm where I finally shifted. RPM dropped to 6200rpm and it killed the lead I had on my opponent who has been a 5.015@140mph. He literally came around me by a fender on the big end.
I think I've also found some power on the big end with timing. My boost starts to fall off around 6400rpm and drops from 28psi at 6200-6400rpm to 26psi by 7000rpm. As the boost pressure falls so will air mass, and subsequently cylinder pressure. Adding a .5 degree at 6400rpm and a full degree at 6800rpm to red line picked me up from a consistent 1.79-1.80 back half to a 1.78-1.79 back half. That is difference between a 136-137mph pass and a 137-138mph pass.
Can't wait to put the solid roller cam in it and find some more power that we need to run the MPH the fast guys are running. With the solid roller I feel we can run 139-140mph.
I am going to probably be selling my A2A intercooler pretty soon though. I feel that it would work absolutely great on a street car that was constantly moving and letting cool air flow over it, but on my car it's turned into a giant heat sink.
I might be able to keep some fans on it in the pits and cool it down, but on Saturday after I had made one pass on the car, just starting it up in the lanes the IAT's were 120 degrees, and it was only 85 outside. Starting the run at 35* above ambient is absolutely killing me on the big end. So if anyone wants to buy my intercooler for a killer deal, I'll be willing to part ways with it and I guarantee you won't get a deal like this anywhere else.

Then have to haul 100 dollars worth of ice to each and every race we go to? No sir, not this guy.
I'm going the KISS route. Adding two more Walboro 450's that will be in-line to my two 450's I already have in tank. They will be on a hobbs switch as well. Each pump retails for 175 and is also designed for use with ethanol, so it's got to be OK with methanol IMO.
I'm going to buy a sub 300 dollar set of Siemans Deka 80's and buy a LS3 4150 Super Victor intake. Going to have our fab guy weld bungs in the SV for the 80's and use them to idle and stage the car on the trans brake. Then turn the 160's I already have on based off duty cycle with the XFI.
It will be incredibly easy to delete the intercooler and weld a new piece of pipe from the turbo to the TB with the new intake in place. I will keep the spacer and elbow I currently have as well.
When it's all said and done, if someone buys my A2A I will not have to spend one penny out of pocket on all of this. The car will make more power, be more consistent and cost less to keep running as M1 is 3.00 a gallon.

I will NOT be going A2W for damn sure! The last thing I'm going to do, is cut holes in my car, run 30' of piping into it, have to spend tons of money on v-bands, piping, a new intercooler core that will be more expensive than my old one and pay our fabricator to work on it after hours.

You will end up cable with one 455 pump to prime and at least 320lbhr of injector in my opinion.
#893
There are 2 cars in our class that use about 6 GPM and run 220# injectors, so I feel with 240# of injector I'll be good.
Both cars run 140+ mph in the 1/8th.
4 450lph pumps is almost 8 GPM so....looks like it will be plenty.
#896
Man I'm getting conflicting info.
One guy who has been 5.0's@140 says I only need 6-7 GPM and that I might be able to make it work with 240# of injector.
The other guy who has been 5.0's@140 has a 13 GPM pump and runs 325# injectors, but is only at 60% IDC.
I need to talk to a professional about this it seems. Hah!
I really would like to not have to do a ton of work on the car at this point in the season, I was mainly look for a KISS way to improve upon the current sitation. A belt drive and a fuel cell would be the best route, but the most expensive and take the most fabrication work.

I been there.
Same thing with ethanol.
One guy says this pump and these injectors will go to 1000rwhp
Another guy says 800rwhp
The I do it and I max it out at 600. Lol
I think so much crap is involved. Like size of fittings, angles of fittings, electrical system. That you just never know.
#899
This may just be a pipe dream at this point.
Another guy just told me they ran 4.20's with a BBTT in Radial Vs. World/Outlaw Drag Radial class with a 1000gph pump on M1. IIRC they have to weigh 3100-3200# at least so they have to be making no less than 2800-3000HP. I'm just looking for 1300hp or so.
4 450's would get me almost 500gph. The only thing that somewhat worries me is running 4 pumps what happens if one fails?
Then again, what happens if 1 of the pumps I currently run fails? What happens if I just run one pump and it fails? What if my steering shaft falls off and I run into the wall? What if, what if, what if?
With a race car you can literally "what if" yourself to death...
