Re: Fasteddi sbc to merlin 509 swap

Re: Fasteddi sbc to merlin 509 swap

I made some more progress with the forward facing headers going well so far definitely tight and I wish I had the extra cash right now for a manual brake conversion but the tubes come off individually so it should be easy to remove valve covers. Pass side will have much more room.

Mabey a turbo(s) will be going on this fall too.....

Re: Fasteddi sbc to merlin 509 swap

About 9 hrs into them I am done. Just need to finish wrapping them and installing all the tubes. Moving battery to back, got a elec. Water pump installed, have a spacer and a quick fuel brawler 950cfm carb to toss on then well be racing hopefully in a week or probly more like 2.

I made some room on the drivers side really should have done a manual brake swap....

Re: Fasteddi sbc to merlin 509 swap

Just made a order though straub technology's for a top end induction kit. Goal is 700-800hp peak power 7000 rpm. Will be custom promaxx 320cc heads milked to 114cc chambers, custom solid roller, port matched victor jr intake...exc heads flow 375/280 cfm at .700

Very excited to say the least. Has some lead time on the order so may get it on motor this fall or at least this winter. Would love to race it though this fall with new set up. Goals are high 9s which should be easily obtainable with 700 plus hp on my race thirdgen.

Re: Fasteddi sbc to merlin 509 swap

I would order the promaxx heads bare, install my own parts and have a machine shop look at them before install after the issues I had.

Are you going to run the car with the engine the way it is now?

Re: Fasteddi sbc to merlin 509 swap

Headers complete and installed. Firing it up Wednesday hopefully. I'd say about 20 hrs total into the headers including wrapping them. Tig welded out.

Re: Fasteddi sbc to merlin 509 swap

1 year after I got these brakes I'm finally tossing them on. Areospace drag front brakes. Easy to install just had to cut off a bit of weight on the spindle. In total I lost 19 lbs per side from the swap. That's 38 easy lbs of weight loss.

having the strange rear disk brakes already helped this car slow down from 125mph pretty easy, these are just icing on the cake.

Re: Fasteddi sbc to merlin 509 swap

Congratulations, sounds mean. I am starting on my next Trans Am and was going to go with a big block, but in AZ I need A/C and that engine looks like it will crowd out the components. Well, awesome anyway, but just helped me to make a decision. Post the vid up of its first tuned pull.

Re: Fasteddi sbc to merlin 509 swap

Well the car did ok this weekend. 3 passes and none were much of any good. 1st pass [email protected] 1.57 60 foot. This pass was very very lean so i went up 4 jet sizes and also noticed my timing was only 32 so added 5 degrees to bring it in at 37. Assuming that was going to help immensely and get me into the high 10s....well after that I chased ignition box issues the rest of the day finally finding that the 6al box had a loose power wire and was making the car break up down the track because of vibrations with the loose wire.

in 2 weeks I'll be back out there. The thing I did notice is my 60 foot picked up big time from the timing and jet change along with squirters. From 1.57 to a 1.46 on the 2nd pass but the car was breaking up half track becuae of the wiring issue so I'm seeing 10.90s with 60s in the 1.40s

Crappy slip attached. Also weighed car the big block definitly weighed me down. 3520 race weight now.

I'm 191 btw

Re: Fasteddi sbc to merlin 509 swap

Update. Well the cars consistant. [email protected] 3 times in a row yesterday.

noticed its lean on the afr guage and plugs too. 13 5-13.8 afr most of the way down the track. My guess my 7 year old walbro 255 is finally dying. I have some areo. 340lph pumps on hand I plan to toss in. I'm losing out on alot of hp from being so lean ......

I finally weighed the car. 3375 without me race ready. 3560 with me race ready. Heavy car. Alum head swap will drop that a solid 80-100lbs so in excited for the straub stuff to come in the next few weeks.

950+hp ati trans and bolt together tsi 5500 custom stall . Just need the straub stuff and we have a 9 second combo just waiting to go in.

Re: Fasteddi sbc to merlin 509 swap

Just curious why you think it's the fuel pump? Is it not responding to bigger jets?

Re: Fasteddi sbc to merlin 509 swap

So I had a best 1/8 mile of [email protected] not too bad for a boat anchor shifting at 5800rpm lol


Man that's one heavy motor. My car now weighes 3560 race weight... yikes!! Playing with the tune after adding a areo 340lph stelth pump, I was on a [email protected] pass when using run completion. Slip below. I was peddling a bit then on brakes and still broke out. Dangit because I treed the crap outta him. Either way it was a fun weekend at the track

Correct among a few other things.

so I found that the pump filter and strainer was plugged with crap. That pump had been in there for about 6 years of racing exc. So while I was in there I swapped pumps just because.
So keep in mind I ran mid 10s with the pump like this with the sbc....amazing

Re: Fasteddi sbc to merlin 509 swap

Well I got all of the parts I need now to hopefully build a 750 horsepower big block 509.

straub solid roller cam specs in pic.

Promaxx 320cc heads assembled by straub and milled for 114cc chambers. 10:1 compression.

custom ported victor jr intake.

our goal was 700+ hp. Peak hp 6800rpm shift point on car at 7200rpm.

I have a ati 850hp rated trans to toss in with it and a custom tsi bolt together converter built for this engine to stall at 5500

all this stuff will be going in this winter.

Not much. I had them for sale for quite some time. No one wants to pay 1200 bucks for used heads so I'm going to keep them. Lets face it afr are not cheap for a reson. They are the best sbc 550hp or less head out there so mabey one day I'll build another sbc.

Re: Fasteddi sbc to merlin 509 swap

Here are the flow numbers on the heads I got from chris struab. Not too bad for 317cc runners.

Re: Fasteddi sbc to merlin 509 swap

Finally yesterday I began to tear into the 509.

Got the solid roller cam in, the moral sportsman solid rollers in, and checked piston to deck clearence etc.

I need to order head gaskets, then measure the pushrods and send the measurements off to chris straub. Then I'll be able to get all that installed and the new heads on, the new 2 piece timing cover and the motor will be ready to go.

With .400 lobe.. and that durration... wow this cam will be a monster.

Also going with a manual brake booster so I can have some more room arround the drivers side header. The pass side was ridiculously easy to take off thankfully.

The goal is still 9.90s, and in my personal opinion it will be more like 9.60-9.80s but aim high to make sure I can meet my goal.

A Ati custom 950hp rated th350 is installed already along with a custom tsi 5500 rpm bolt together billet converter.

Re: Fasteddi sbc to merlin 509 swap

Heads are off, and heavy 82lbs each or 164lbs a pair. The alum promaxx heads weight 42lbs each or 84lbs total. A bit off the 78lbs promaxx advertises but that might be unassembled.

Just waiting on gaskets ans such then well toss it all back together.

Big difference in the merlin and victor jr intake opening. Helps it was port matched to the heads etc.

Re: Fasteddi sbc to merlin 509 swap

Update just waiting on pushrods to come that I measured for and we can finish tossing it all together.

I am removing the brake booster for a manual set up to allow me some more room arround the headers.

ARP head studs installed over the ole manley bokts. MLS. 027 head gaskets, MLS exhaust gaskets, 2 piece adjustable timing cover, billet full roller timing set, ext.

The goal is by end of March to make this puppy run. Thankfully the hard stuff is done. Cam is degreed and installed to straub specs, cam end play set, push rod length measured.

Still worries me that this car may easily run under 10 flat and require me to do some safety additions to stay legal. Such as a sfi scatter shield, 8pt cage vs the 6pt set up I have now. Etc. I dream of what this car will be like letting of of the brake and the car launches at 5500rpm and I shift at 7k. Wheels up indeed. Which is nothing new for the car but a 1.47 60 foot was my prior best. I would be dissapointed with anything slower then 1.39 60s.

The one good thing is everything drive train wise can handle the tq and hp. ATI 950HP rated trans (David Caine from ATI is behind me to see how this set up does. He did a few custom things to the trans to extend lift and free up hp.) Its not a off the shelf trans by any means. 1200HP rated strange S60 rear end, 1200HP chrome moly 3.5 inch D. SHAFT. etc.
